Copy the Sign of Given Number in Golang Last Updated : 01 Apr, 2020 Comments Improve Suggest changes Like Article Like Report 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 are allowed to copy the sign of the specified number with the help of Copysign() 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 Copysign() function. Syntax: func Copysign(a, b float64) float64 Here, this function returns a value with the magnitude of a and the sign of b. Example 1: C // Golang program to illustrate how to // copy the sign of the given number package main import ( "fmt" "math" ) // Main function func main() { // Copying the sign of the // given numbers // Using Copysign() function res_1 := math.Copysign(2, -3) res_2 := math.Copysign(-8, 1) res_3 := math.Copysign(-67, -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: -2.0 Result 2: 8.0 Result 3: -67.0 Example 2: C // Golang program to illustrate how to // copy the sign of the given number package main import ( "fmt" "math" ) // Main function func main() { // Copying the sign of // the given numbers // Using Copysign() function nvalue_1 := math.Copysign(3, -1) nvalue_2 := math.Copysign(-4, 3) res := nvalue_1 + nvalue_2 fmt.Printf("%.1f + %.1f = %.1f", nvalue_1, nvalue_2, res) } Output: -3.0 + 4.0 = 1.0 Comment More infoAdvertise with us Next Article Copy the Sign of Given Number in Golang K Kirti_Mangal Follow Improve Article Tags : Go Language Golang-Math Similar Reads Finding the Square Root 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.
