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 decimal logarithm of the specified complex number with the help of Log10() 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 Log10() function.
Syntax:
func Log10(y complex128) complex128
Example 1:
// Golang program to illustrate how to find the // decimal logarithm of the given complex number package main import ( "fmt"
"math/cmplx"
) // Main function func main() { // Finding decimal logarithm of
// the specified complex number
// Using Log10() function
res_1 := cmplx.Log10(1i)
res_2 := cmplx.Log10(-4 + 12i)
res_3 := cmplx.Log10(-3 - 9i)
// 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: (0.0+0.7i) Result 2: (1.1+0.8i) Result 3: (1.0-0.8i)
Example 2:
// Golang program to illustrate how to find the // decimal logarithm of the given complex number package main import ( "fmt"
"math/cmplx"
) // Main function func main() { cnumber_1 := complex(0, 2)
cnumber_2 := complex(4, 6)
// Finding decimal logarithm
cvalue_1 := cmplx.Log10(cnumber_1)
cvalue_2 := cmplx.Log10(cnumber_2)
// Sum of the given values
res := cvalue_1 + cvalue_2
// Displaying results
fmt.Println( "Complex Number 1: " , cnumber_1)
fmt.Printf( "Decimal logarithm 1: %.1f" , cvalue_1)
fmt.Println( "\nComplex Number 2: " , cnumber_2)
fmt.Printf( "Decimal logarithm 2: %.1f " , cvalue_2)
fmt.Printf( "\nSum : %.1f" , res)
} |
Output:
Complex Number 1: (0+2i) Decimal logarithm 1: (0.3+0.7i) Complex Number 2: (4+6i) Decimal logarithm 2: (0.9+0.4i) Sum : (1.2+1.1i)
