DESCRIPTIONThetanh (), tanhf (), and
tanhl () functions compute the hyperbolic tangent of
x. For a discussion of error due to roundoff, see
math(3).
RETURN VALUESThetanh (), tanhf (), and the
tanhl () functions return the hyperbolic tangent value.
SEE ALSOacos(3), asin(3), atan(3), atan2(3), cos(3), cosh(3), ctanh(3), math(3), sin(3), sinh(3), tan(3)STANDARDSThetanh () function conforms to ISO/IEC
9899:1990 (“ISO C90”).
