math.Remainder() Function in Golang With Examples
Last Updated :

Go language provides inbuilt support for basic constants and mathematical functions to perform operations on the numbers with the help of the math package. You can find the remainder or the IEEE 754 floating-point remainder of a/b with the help of Remainder() function provided by the math package. So, you need to add a math package in your program with the help of the import keyword to access the Remainder() function.
Syntax:
func Remainder(a, b float64) float64
- If you pass -Inf or +Inf in this function like Remainder(-Inf, b) or Remainder(+Inf, b), then this function will return NaN.
- If you pass NaN in this function like Remainder(NaN, b), then this function will return NaN.
- If you pass b=0 in this function like Remainder(a, 0), then this function will return NaN.
- If you pass -Inf or +Inf in this function like Remainder(a, -Inf) or Remainder(b, +Inf), then this function will return a.
- If you pass NaN in this function like Remainder(a, NaN), then this function will return NaN.
Example 1:
package main
import (
"fmt"
"math"
)
func main() {
res_1 := math.Remainder(36, 5)
res_2 := math.Remainder(-100, 100)
res_3 := math.Remainder(45.6, 8.9)
res_4 := math.Remainder(math.NaN(), 67)
res_5 := math.Remainder(math.Inf(1), 67)
fmt.Printf( "Result 1: %.1f" , res_1)
fmt.Printf( "\nResult 2: %.1f" , res_2)
fmt.Printf( "\nResult 3: %.1f" , res_3)
fmt.Printf( "\nResult 4: %.1f" , res_4)
fmt.Printf( "\nResult 5: %.1f" , res_5)
}
|
Output:
Result 1: 1.0
Result 2: -0.0
Result 3: 1.1
Result 4: NaN
Result 5: NaN
Example 2:
package main
import (
"fmt"
"math"
)
func main() {
nvalue_1 := math.Remainder(49, 6)
nvalue_2 := math.Remainder(56.7, 3)
res := nvalue_1 + nvalue_2
fmt.Printf( "%.2f + %.2f = %.2f" ,
nvalue_1, nvalue_2, res)
}
|
Output:
1.00 + -0.30 = 0.70
