Finding Mod of Given Number in Golang

Last Updated : 13 Apr, 2020

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.

Example 1:

// Golang program to illustrate how to 
// find mod of the specified numbers 
  
package main 
  
import ( 
    "fmt"
    "math"
) 
  
// 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) 
  
} 

Output:

Result 1: 0.0
Result 2: -0.0
Result 3: 1.1
Result 4: NaN
Result 5: NaN

Example 2:

// Golang program to illustrate how to 
// find mod of the specified numbers 
  
package main 
  
import ( 
    "fmt"
    "math"
) 
  
// Main function 
func main() { 
  
    // Finding mod of  
    // the given numbers 
    // Using Mod() function 
    nvalue_1 := math.Mod(34, 6) 
    nvalue_2 := math.Mod(56.7, 3.4) 
  
    // Finding sum of the given mod 
    res := nvalue_1 + nvalue_2 
    fmt.Printf("%.2f + %.2f = %.2f",  
            nvalue_1, nvalue_2, res) 
  
}
