Functions

func Abs

func Abs(x complex64) float32

Abs returns the absolute value (also called the modulus) of x.

func Conj

func Conj(x complex64) complex64

Conj returns the complex conjugate of x.

func Inf

func Inf() complex64

Inf returns a complex infinity, complex(+Inf, +Inf).

func IsInf

func IsInf(x complex64) bool

IsInf returns true if either real(x) or imag(x) is an infinity.

func IsNaN

func IsNaN(x complex64) bool

IsNaN returns true if either real(x) or imag(x) is NaN and neither is an infinity.

func NaN

func NaN() complex64

NaN returns a complex “not-a-number” value.

func Sqrt

func Sqrt(x complex64) complex64

Sqrt returns the square root of x. The result r is chosen so that real(r) ≥ 0 and imag(r) has the same sign as imag(x).
