What is the strconv.IntSize constant in Golang?

Golang strconv.IntSize constant

The strconv package IntSize constant is used to get the size in bits of an int or uint value. The size in bits of an int or uint of uint type is machine-dependent.

Syntax

int strconv.IntSize

Return value

The strconv.IntSize constant returns the bit size of an int or uint value.

Code

The following code shows us how to display the return type and value of the strconv.IntSize constant in Golang.

// Using Size Constant in Golang
package main
import (
	"fmt"
	"strconv"
)
func main() {
  // display the number of bits in an int
	fmt.Println(strconv.IntSize)
  // display return type
  fmt.Printf("The return type of strconv.IntSize: %T\n", strconv.IntSize)
}

Explanation

  • Line 3: We add the main package.
  • Lines 5–8: We import the necessary packages.
  • Lines 10–17: We define the main() function. Then, we print the return type of strconv.IntSize and the number of bits in an int.
