NAME

conj — complex conjugation function

SYNOPSIS

#include <complex.h>

double complex
conj(double complex z);

long double complex
conjl(long double complex z);

float complex
conjf(float complex z);

DESCRIPTION

conj(z) computes the complex conjugate of a complex floating-point number z.

If z = x+iy, then conj(z) = x-iy.

NOTES

If y is NaN, conj(x+yi) = x-yi; the sign bit of the NaN has been changed.

STANDARDS

The conj() function conforms to ISO/IEC 9899:2011.
