NAME

6       conj, conjf, conjl - calculate the complex conjugate
7

SYNOPSIS

9       #include <complex.h>
10
11       double complex conj(double complex z);
12       float complex conjf(float complex z);
13       long double complex conjl(long double complex z);

DESCRIPTION

18       These  functions  return the complex conjugate value of z.  That is the
19       value obtained by changing the sign of the imaginary part.
20
21       One has:
22
23           cabs(z) = csqrt(z * conj(z))
24

VERSIONS

26       These functions first appeared in glibc in version 2.1.
