GoLang – Find the floating-point remainder – Mod() Function – Examples & Explanation

The syntax of Mod() function in Go Language is:

func Mod(x, y float64) float64

Note: float64 is a data type in Go language which has IEEE-754 64-bit floating-point numbers.
Special cases are:
Mod(±Inf, y) = NaN
Mod(NaN, y) = NaN
Mod(x, 0) = NaN
Mod(x, ±Inf) = x
Mod(x, NaN) = NaN

x, y – Where x and y are Valid float64 Input valued. These parameters are required.

If the x or y parameter are not number (numeric values) Mod() function returns an error .
If there is no argument (x or y – input values) passes to the function, then the compiler will produce an error.

Mod() function will returns the floating-point remainder of x/y. The magnitude of the result is less than y and its sign agrees with that of x.

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Mod(-8, 66)
	fmt.Println(x)
}

Output:
-8

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Mod(7, 4)
	fmt.Println(x)
}

Output:
3

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Mod(-8, -3.4)
	fmt.Println(x)
}

Output:
-1.2000000000000002
