CASIN(3M) Mathematical Library Functions CASIN(3M)

NAME

casin, casinf, casinl - complex arc sine functions

SYNOPSIS

c99 [ flag... ] file... -lm [ library... ]
#include <complex.h>

double complex casin(double complex z);


float complex casinf(float complex z);


long double complex casinl(long double complex z);

DESCRIPTION

These functions compute the complex arc sine of z, with branch cuts
outside the interval [ -1, +1 ] along the real axis.

RETURN VALUES

These functions return the complex arc sine value, in the range of a
strip mathematically unbounded along the imaginary axis and in the
interval [ -pi/2, +pi/2 ] along the real axis.

ERRORS

No errors are defined.
