TANH(3F)TANH(3F)NAME
tanh, dtanh, qtanh - FORTRAN hyperbolic tangent intrinsic function
SYNOPSIS
real r1, r2
double precision dp1, dp2
real*16 qp1, qp2
r2 = tanh(r1)
dp2 = dtanh(dp1)
dp2 = tanh(dp1)
qp2 = qtanh(qp1)
qp2 = tanh(qp1)DESCRIPTION
tanh returns the real hyperbolic tangent of its real argument, dtanh
returns the double-precision hyperbolic tangent of its double-precision
argument, and qtanh returns the real*16 hyperbolic tangent of its real*16
argument. The generic form tanh may be used to return a double-precision
value when given a double-precision argument, or a real*16 value when
given a real*16 argument.
