complx.IsNaN() Function in Golang With Examples

In Go language, cmplx packages supply basic constants as well as mathematical functions for the complex numbers. The IsNaN() function in Go language is used to check if either the stated real(x) or imag(x) is NaN or not and is neither an infinity. Moreover, this function is defined under the cmplx package. Here, you need to import “math/cmplx” package in order to use these functions.

Syntax:

func IsNaN(x complex128) bool

Here, x is the set of all complex numbers with float64 real as well as imaginary parts.

Return value: It returns true if x is NaN else it returns false.

Example 1:

// Golang program to illustrate the usage of
// IsNaN() function

// Including main package
package main

// Importing fmt and math/cmplx
import (
    "fmt"
    "math/cmplx"
)

// Calling main
func main() {

    // Returns output
    fmt.Println(cmplx.IsNaN(3 + 4i))
}

Output:

false

Example 2:

// Golang program to illustrate the usage of
// IsNaN() function

// Including main package
package main

// Importing fmt and math/cmplx
import (
    "fmt"
    "math/cmplx"
)

// Calling main
func main() {

    // Returns output
    fmt.Println(cmplx.IsNaN(-0i / 8))
}

Output:

false
