These functions compute the complex hyperbolic tangent of <[z]>.
|
||||
|
||||
<<ctanhf>> is identical to <<ctanh>>, except that it performs
|
||||
its calculations on <<floats complex>>.
|
||||
|
||||
RETURNS
|
||||
These functions return the complex hyperbolic tangent value.
|
||||
|
||||
PORTABILITY
|
||||
<<ctanh>> and <<ctanhf>> are ISO C99
|
||||
|
||||
QUICKREF
|
||||
<<ctanh>> and <<ctanhf>> are ISO C99
