math.Dim() Function in Golang With Examples

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
