double complex catanh(double complex z);float complex catanhf(float complex z);
long double complex catanhl(long double complex z);DESCRIPTION
These functions compute the complex arc hyperbolic tangentof z, with branch cuts outside the interval [ -1, +1 ] along
the real axis.RETURN VALUES
These functions return the complex arc hyperbolic tangent value, in the range of a strip mathematically unboundedalong the real axis and in the interval [ -ipi/2, +ipi/2 ]
along the imaginary axis.ERRORS
No errors are defined.ATTRIBUTES
