How to use operators with numbers in the Go programming language? Do you know how to use operators with numbers in Golang? If not, then you don’t need to worry because, in this article, I will tell you How to use operators with numbers in Golang.
Go is an imperative, object-oriented language. While this makes it a great language for programming in Go, it is not the easiest language to program in. In this post, I demonstrate how to use operators with numbers.
In Go, numbers are represented in decimal format, and Go supports four different types of numbers: float, int, uint, and complex. You can think of a number as a tuple of two types, where the first type is the base and the second type is the exponent. For example, the number 6.6 would be represented as a tuple of type (6,.6), where the first number is 6, and the second number is.6.
Go provides a set of operators that can be applied to numbers. These include addition (+), multiplication (*), subtraction (-), division (/) and modulus (%) operators.
What is an Operator?
An operator is a symbol that is used to perform an action on a number. The list of operators is long and you can use any one of the operators as per your requirement. Some of the common operators are as follows:
+ +
- -
* /
%
& | & ^
<< >>
==!= <= >= < >
&& ||
++ --
+= -= *= /= %= &= ^=
<= >=
The use of these operators is very simple, if you use two operators, then you can operate like you can use the + sign to add two numbers. If you want to know the result of the sum then you have to use the & sign.
Types of Operators in Go Programming language
The operator is used to check the conditions or make some calculations. There are many types of operators available, here I will tell you about the most popular ones.
Arithmetic operators:
These are the most common operators that you will use in the Golang programming language. These operators are used to calculate the value of the expressions. They are as follows:
+ (Addition)
– (Subtraction)
* (Multiplication)
/ (Division)
^ (Exponentiation)
Assignment operator:
If you want to assign a variable with some value then you can use the assignment operator. This is written as:
= (Assignment Operator)
Comparison operators:
Comparison operators compare two values and return a boolean value. The comparison operators are as follows:
== (Equality)
!= (Not equal)
> (Greater than)
< (Less than)
Greater than and less than are written as > and < respectively.
Logical operators:
The logical operators evaluate the truth of a Boolean expression. They are as follows:
|| (Or)
&& (And)
! (Not)
Ternary operators:
Ternary operators are the operators that have three arguments. The three arguments are evaluated and the result is returned. The ternary operators are as follows:
? : (Question mark colon)
There are some other operators as well, but the above ones are the most common.
Operator precedence
The order of the operation has been defined in the order of the precedence. You can see the precedence of the operator by adding the numbers after the name of the operator. So, if you want to know the precedence of the multiplication operator, then you have to add 2 to the name of the operator.
Here are some of the examples of the operators:
1 + 1 = 2
1 - 1 = 0
2 / 2 = 1
4 % 4 = 0
4 & 4 = 4
8 ^ 8 = 16
4 << 2 = 8
5 == 5 = true
As you know that Golang is a programming language that originated in Google, which is known for its powerful programming tools. This language is not only a great tool but also a programming language that uses many useful and common operators. Here we list the most important operators with numbers in the golang programming language.
Addition operator with numbers in golang Programming language:
The addition is a binary operator that means adding two values together. The addition operator is written with a plus sign (+) or a plus sign followed by a space and then the operands. For example, 4 + 5 is the same as 4 + 5. The value of the expression is the sum of the values of the operands.
Subtraction operator with numbers in golang Programming language:
Subtraction is a binary operator that means subtracting one value from another. The subtraction operator is written with a minus sign (-) or a minus sign followed by a space and then the operands. For example, 4 – 5 is the same as 4 – 5. The value of the expression is the difference between the values of the operands.
Multiplication operator with numbers in golang Programming language:
Multiplication is a binary operator that means multiplying two values. The multiplication operator is written with an asterisk (*) or a star sign (*) followed by a space and then the operands. For example, 4 * 5 is the same as 4 * 5. The value of the expression is the product of the values of the operands.
Division operator with numbers in golang Programming language:
The division is a binary operator that means dividing one value by another. The division operator is written with a forward slash (/), a space, and then the operands. For example, 4 / 5 is the same as 4 / 5. The value of the expression is the quotient of the values of the operands.
Modulus operator with numbers in golang Programming language:
Modulus is a binary operator that means finding the remainder of the division of one number by another. The modulus operator is written with a forward slash (/), a space, and then the operands. For example, 4 % 5 is the same as 4 % 5. The value of the expression is the remainder of the division of the first operand by the second.
Floor function with numbers in golang Programming language:
The floor function is used to find the lowest whole number that is greater than or equal to the given real value. The floor function is written with a forward slash (/), a space, and then the operands. For example, 4 / 5 is the same as 4 / 5. The value of the expression is the smallest integer that is greater than or equal to the value of the first operand and not greater than the value of the second operand.
Ceiling function with numbers in golang Programming language:
The ceiling function is used to find the largest whole number that is less than or equal to the given real value. The ceiling function is written with a forward slash (/), a space, and then the operands. For example, 4 / 5 is the same as 4 / 5. The value of the expression is the largest integer that is less than or equal to the value of the first operand and not less than the value of the second operand.
Round function with numbers in golang Programming language:
The round function is used to find the nearest whole number to the given real value. The round function is written with a forward slash (/), a space, and then the operands. For example, 4 / 5 is the same as 4 / 5. The value of the expression is the closest integer to the value of the first operand that is equal to the value of the second operand.
Floor ceiling functions with numbers in golang Programming language:
The floor ceiling function is used to find the smallest or largest integer that is greater than or equal to the given real value. The floor ceiling function is written with a forward slash (/), a space, and then the operands. For example, 4 / 5 is the same as 4 / 5. The value of the expression is the smallest integer that is greater than or equal to the value of the first operand and not less than the value of the second operand.
How to apply Operators with numbers in GO programming language
When you apply an operator to a number, it is always evaluated from left to right. For example, the following snippet shows the output of applying the + operator to the numbers 5 and 6.
package main
import (
"fmt"
)
func main() {
n1 := 5
n2 := 6
fmt.Println(n1+n2)
}
In the above snippet, the + operator is being applied to the numbers 5 and 6. Because the operator is being applied to the numbers from left to right, the first operand is evaluated first. The result of evaluating the first operand is then added to the second operand. The result of the evaluation of the second operand is then added to the result of the evaluation of the first operand. This is why it is called a left-associative operator.
Here is a more complicated example showing how multiple operands can be added together to get the result of applying the + operator to the numbers 5 and 6.
package main
import (
"fmt"
)
func main() {
n1 := 5
n2 := 6
fmt.Println(n1+n2)
}
The above snippet shows how the result of the first operand of the + operator is added to the second operand, and the result of the second operand is added to the result of the evaluation of the first operand. This is why it is called a left-associative operator.
You can also add a number to a variable. For example, the following snippet adds the variable n to the number 1.
package main
import (
"fmt"
)
func main() {
n := 1
fmt.Println(n + n)
}
While the above snippet works, it is not very useful. It is better to store the value of the number and add it to the variable.
Here is another example where we are adding a variable to a number. The following snippet adds the number 10 to the variable n.
package main
import (
"fmt"
)
func main() {
n := 10
fmt.Println(n + n)
}
The above snippet also works, but it is more readable when written as the following snippet.
package main
import (
"fmt"
)
func main() {
n := 10
fmt.Println(n + n)
}
In the above snippet, the number 10 is added to the variable n. This means that the variable n is first assigned the number 10. Then, the number 10 is added to the variable n.
This can be generalized as shown below. The following snippet adds the variable x to the number y.
package main
import (
"fmt"
)
func main() {
x := 10
y := 20
fmt.Println(x + y)
}
You can also add a number to a variable. For example, the following snippet adds the variable x to the number y.
package main
import (
"fmt"
)
func main() {
x := 10
y := 20
fmt.Println(x + y)
}
Here is a more complicated example showing how you can add the variable x to the number y.
package main
import (
"fmt"
)
func main() {
x := 10
y := 20
fmt.Println(x + y)
}
