catan(3M) Mathematical Library Functions catan(3M)NAMEcatan, catanf, catanl - complex arc tangent functionsSYNOPSIScc [ flag... ] file... -lm [ library... ] #include <complex.h> double complex catan(double complex z); float complex catanf(float complex z); long double complex catanl(long double complex z);DESCRIPTIONThese functions compute the complex arc tangent of z, with branch cuts outside the interval [ -i, +++++i ] along the imaginary axis.RETURN VALUESThese functions return the complex arc tangent value, in the range of a strip mathematically unbounded along the imaginary axis and in the interval [ -/2, +/2 ] along the real axis.ERRORSNo errors are defined.ATTRIBUTESSee attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+SEE ALSOcomplex.h(3HEAD), ctan(3M), attributes(5), standards(5) SunOS 5.10 1 Sep 2002 catan(3M)
