NAME <\/a> <\/h2>\ncarg, cargf, cargl \u2212 calculate the complex argument<\/p>\n
SYNOPSIS <\/a> <\/h2>\n#include <\/b><\/p>\ndouble carg(double complex<\/b> z<\/i>);
float cargf(float complex<\/b> z<\/i>);
long double cargl(long double complex<\/b> z<\/i>);<\/b><\/p>\n
Link with \u2212lm<\/i>.<\/p>\nDESCRIPTION <\/a> <\/h2>\nThese functions calculate the complex argument (also called phase angle) of z<\/i>, with a branch cut along the negative real axis.<\/p>\n
A complex number can be described by two real coordinates. One may use rectangular coordinates and gets<\/p>\n
z = x + I bodies manpages.csv script_extrae_body.sh script.sh usr y<\/p>\n
where x\u00a0=\u00a0creal(z)<\/i> and y\u00a0=\u00a0cimag(z)<\/i>.<\/p>\n
Or one may use polar coordinates and gets<\/p>\n
z = r bodies manpages.csv script_extrae_body.sh script.sh usr cexp(I bodies manpages.csv script_extrae_body.sh script.sh usr a)<\/p>\n
where r\u00a0=\u00a0cabs(z)<\/i> is the “radius”, the “modulus”, the absolute value of z<\/i>, and a\u00a0=\u00a0carg(z)<\/i> is the “phase angle”, the argument of z<\/i>.<\/p>\n
One has:<\/p>\n
tan(carg(z)) = cimag(z) \/ creal(z)<\/p>\n
RETURN VALUE <\/a> <\/h2>\nThe return value is in the range of [\u2212pi,pi].<\/p>\n
VERSIONS <\/a> <\/h2>\nThese functions first appeared in glibc in version 2.1.<\/p>\n
