.Sh DESCRIPTION
|
|
The
|
|
.Fn ccosh ,
|
|
.Fn csinh ,
|
|
and
|
|
.Fn ctanh
|
|
functions compute the hyperbolic cosine, sine, and tangent of the complex number
|
|
.Fa z ,
|
|
respectively.
|
|
The
|
|
.Fn ccoshf ,
|
|
.Fn csinhf ,
|
|
and
|
|
.Fn ctanhf
|
|
functions perform the same operations in
|
|
.Fa float
|
|
precision.
