In this tutorial, we will learn about the int8 data type in Go. We will cover the basics of defining and using int8 values, including how to perform arithmetic operations and compare 8-bit integers.
The int8
data type in Go is used to represent 8-bit signed integer values. The range of an int8
is from -128 to 127.
Int8 variables in Go can be defined using the var
keyword or by type inference with explicit type conversion.
var x int8 = 127
y := int8(-128)
Arithmetic operations such as addition, subtraction, multiplication, and division can be performed on int8 values.
sum := x + y
difference := x - y
product := x * y
quotient := x / y
Int8 values can be compared using relational operators.
fmt.Println(x > y)
fmt.Println(x < y)
fmt.Println(x == y)
We can define and use int8 variables in Go to represent 8-bit signed integer values.
For example,
x
and assign it a value.y
using type inference with explicit type conversion and assign it a value.package main
import "fmt"
func main() {
var x int8 = 127
y := int8(-128)
fmt.Println(x)
fmt.Println(y)
}
127 -128
We can perform arithmetic operations on int8 values in Go.
For example,
x
and y
.package main
import "fmt"
func main() {
x := int8(127)
y := int8(-128)
sum := x + y
difference := x - y
product := x * y
quotient := x / y
fmt.Println("Sum:", sum)
fmt.Println("Difference:", difference)
fmt.Println("Product:", product)
fmt.Println("Quotient:", quotient)
}
Sum: -1 Difference: -1 Product: -16256 Quotient: -1
We can compare int8 values in Go using relational operators.
For example,
x
and y
with different values.package main
import "fmt"
func main() {
x := int8(127)
y := int8(-128)
fmt.Println(x > y) // true
fmt.Println(x < y) // false
fmt.Println(x == y) // false
}
true false false
We can pass int8 values to functions and return int8 values from functions in Go.
For example,
multiply
that takes two int8 parameters and returns their product.package main
import "fmt"
func multiply(a int8, b int8) int8 {
return a * b
}
func main() {
result := multiply(12, 10)
fmt.Println(result)
}
