ctanh(3M)ctanh(3M)NAMEctanh(), ctanhf(), ctanhl(), ctanhw(), ctanhq() - complex hyperbolic
tangent functions
SYNOPSISDESCRIPTION
These functions are available only for Integrity servers.
returns the complex hyperbolic tangent of z.
is a version of it takes a argument and returns a result.

is an version of it takes an argument and returns an result.
is equivalent to on HP-UX systems.
USAGE
To use these functions, compile with the default option. To use com‐
pile with the option. Make sure your program includes Link in the math
library by specifying on the compiler or linker command line.
RETURN VALUE
= and is odd.
returns +0+i0.
returns NaN+iNaN and raises the invalid floating-point exception, for
finite x.
returns NaN+iNaN and optionally raises the invalid floating-point
exception, for finite x.
returns for positive-signed finite y.
(where the sign of the imaginary part of the result is unspecified).
(where the sign of the imaginary part of the result is unspecified).
returns NaN+i0.
returns NaN+iNaN and optionally raises the invalid floating-point
exception, for all nonzero numbers y.
returns NaN+iNaN.
ERRORS
