Tangent functions.
gentype tan(gentype)
gentype tanh(gentype)
gentype tanpi(gentype x)
gentype half_tan(gentype x)
gentype native_tan(gentype x)
tan
computes the tangent.
tanh
computes the hyperbolic tangent.
tanpi
computes tan
(pi * x
).
half_tan
computes tangent.
x
must be in the range -216… +216.
native_tan
computes tangent over an implementation-defined range.
The maximum error is implementation-defined.
