The Remainder() function returns the remainder of the division of two given values. The remainder may be a whole or a floating-point number.

Syntax

result := math.Remainder(num1, num2)

math.Remainder() returns the whole or IEEE 754 floating-point remainder of num1 divided by num2, except in four special cases:

  • If num1 equals +-Inf the function will return NaN.
  • If num2 equals +-Inf the function returns num1.
  • If either argument is NaN the function will return NaN.
  • If num2 equals 0 the function will return NaN.

Example

This example divides two integer values and returns the remainder result.

package main
import (
"fmt"
"math"
)
func main() {
result := math.Remainder(2, 35)
fmt.Printf("%.1f\n", result)
}

This will return:

2.0

Codebyte Example

The following example can be run and uses the math.Remainder() function to return the remainder of two given values. The second call is an example of a special case and returns NaN.
