Go language provides inbuilt support for basic constants and mathematical functions for complex numbers with the help of the cmplx package. You are allowed to find the absolute value of the specified complex number with the help of Abs() function provided by the math/cmplx package. So, you need to add a math/cmplx package in your program with the help of the import keyword to access the Abs() function.
Syntax:
func Abs(a complex128) float64
Let us discuss this concept with the help of the given examples:
Example 1:
// Golang program to illustrate // how to find absolute value package main import ( "fmt"
"math/cmplx"
) // Main function func main() { // Finding absolute value of
// the specified complex number
// Using Abs() function
res_1 := cmplx.Abs(3 + 5i)
res_2 := cmplx.Abs(-4 + 8i)
res_3 := cmplx.Abs(-8 - 7i)
// Displaying the result
fmt.Println( "Random Number 1:" , res_1)
fmt.Println( "Random Number 2: " , res_2)
fmt.Println( "Random Number 3: " , res_3)
} |
Output:
Random Number 1: 5.8309518948453 Random Number 2: 8.94427190999916 Random Number 3: 10.63014581273465
Example 2:
// Golang program to illustrate how // to find absolute value package main import ( "fmt"
"math/cmplx"
) // Main function func main() { // Complex numbers
cnumber_1 := complex(5, 7)
cnumber_2 := complex(6, 9)
// Finding absolute values
absvalue_1 := cmplx.Abs(cnumber_1)
absvalue_2 := cmplx.Abs(cnumber_2)
// Sum of two absolute values
res := absvalue_1 + absvalue_2
// Displaying results
fmt.Println( "Complex Number 1: " , cnumber_1)
fmt.Println( "Complex Number 2: " , cnumber_2)
fmt.Println( "Sum of the absolute values of " +
"the given complex numbers: " )
fmt.Printf( "%.1f + %.1f = %.1f" , absvalue_1, absvalue_2, res)
} |
Output:
Complex Number 1: (5+7i) Complex Number 2: (6+9i) Sum of the absolute values of the given complex numbers: 8.6 + 10.8 = 19.4
