GoLang – Find Floating Point Remainder – Remainder() Function – Examples & Explanation

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

func Remainder(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:
Remainder(±Inf, y) = NaN
Remainder(NaN, y) = NaN
Remainder(x, 0) = NaN
Remainder(x, ±Inf) = x
Remainder(x, NaN) = NaN

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

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

Remainder() function will return the IEEE 754 floating-point remainder of x/y.

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Remainder(-11, 2)
	fmt.Println(x)
}

Output:
1

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Remainder(2, 13)
	fmt.Println(x)
}

Output:
2

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Remainder(-15, -6.21)
	fmt.Println(x)
}

Output:
-2.58
