Comparison Operators

We discussed three comparison operators in previous chapters. However, there are additional operators in this category that we should be familiar with. Below is a list of all the comparison operators:

Operator	Logic
`==`	Equal to
`!=`	Not Equal to
`<`	Less Than
`<=`	Less Than or Equal to
`>`	Greater Than
`>=`	Greater Than or Equal to

Not Equal To (!=)

This operator is used to check if two values are not equal to each other. For example:

index.go


              12
            
var a int = 1
fmt.Println(a != 2) // Outputs 'true'

Less Than or Equal To (<=)

This operator is used to check if the value on the left is less than or equal to the value on the right:

index.go


              123
            
var a int = 7
fmt.Println(a <= 7) // Outputs 'true'
fmt.Println(a <= 6) // Outputs 'false'

Greater Than or Equal To (>=)

This operator is used to check if the value on the left is greater than or equal to the value on the right:

index.go


              123
            
var a int = 7
fmt.Println(a >= 7) // Outputs 'true'
fmt.Println(a >= 6) // Outputs 'true'

Was alles duidelijk?
