Finding Mod of Given Number in Golang

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 a mod or floating-point remainder of specified a/b with the help of Mod() 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 Mod() function.

Syntax:

func Min(a, b float64) float64
  • In this function, the magnitude of the result is less than b and its sign agrees with that of a.
  • If you pass -Inf or +Inf in this function like Mod(-Inf, b) or Mod(+Inf, b), then this function will return NaN.
  • If you pass NaN in this function like Mod(NaN, b), then this function will return NaN.
  • If you pass b=0 in this function like Mod(a, 0), then this function will return NaN.
  • If you pass -Inf or +Inf in this function like Mod(a, -Inf) or Mod(b, +Inf), then this function will return a.
  • If you pass NaN in this function like Mod(a, NaN), then this function will return NaN.

// Main function
func main() {
  
    // Finding mod of the given numbers
    // Using Mod() function
    res_1 := math.Mod(60, 5)
    res_2 := math.Mod(-100, 100)
    res_3 := math.Mod(45.6, 8.9)
    res_4 := math.Mod(math.NaN(), 67)
    res_5 := math.Mod(math.Inf(1), 67)
  
    // Displaying the result
    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)
  
}
