Finding Absolute Value For Specified Complex Number in Golang?
Last Updated :

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:
package main
import (
"fmt"
"math/cmplx"
)
func main() {
res_1 := cmplx.Abs(3 + 5i)
res_2 := cmplx.Abs(-4 + 8i)
res_3 := cmplx.Abs(-8 - 7i)
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:
package main
import (
"fmt"
"math/cmplx"
)
func main() {
cnumber_1 := complex(5, 7)
cnumber_2 := complex(6, 9)
absvalue_1 := cmplx.Abs(cnumber_1)
absvalue_2 := cmplx.Abs(cnumber_2)
res := absvalue_1 + absvalue_2
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
