math.Dim() Function in Golang With Examples

Last Updated : 01 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. Dim() function provided by the math package return the maximum of a-b or 0. So, to access this function you need to add a math package in your program with the help of the import keyword.

Syntax:

 func Dim(a, b float64) float64

If you pass Inf in this function like Dim(+Inf, +Inf), then this function will return NaN.
If you pass -Inf in this function like Dim(-Inf, -Inf), then this function will return NaN.
If you pass NaN in this function like Dim(a, NaN) or Dim(NaN, b), then this function will return NaN.

Example 1:

// Golang program to illustrate the dim function 
package main 
  
import ( 
    "fmt"
    "math"
) 
  
// Main function 
func main() { 
  
    // Using Dim() function 
    res_1 := math.Dim(2, -3) 
    res_2 := math.Dim(8, -1) 
    res_3 := math.Dim(-4, -2) 
  
    // Displaying the result 
    fmt.Printf("Result 1: %.1f", res_1) 
    fmt.Printf("\nResult 2: %.1f", res_2) 
    fmt.Printf("\nResult 3: %.1f", res_3) 
  
} 

Output:

Result 1: 5.0
Result 2: 9.0
Result 3: 0.0

Example 2:

// Golang program to illustrate the dim function 
package main 
  
import ( 
    "fmt"
    "math"
) 
  
// Main function 
func main() { 
  
    // Using Dim() function 
    nvalue_1 := math.Dim(3, -1) 
    nvalue_2 := math.Dim(4, 3) 
    res := nvalue_1 + nvalue_2 
    fmt.Printf("%.1f + %.1f = %.1f", 
            nvalue_1, nvalue_2, res) 
  
} 

Output:

4.0 + 1.0 = 5.0
