NAME
1.27 `sinh', `sinhf'--hyperbolic sine
SYNOPSIS
#include <math.h>
double sinh(double X);
float sinhf(float X);
DESCRIPTION
`sinh' computes the hyperbolic sine of the argument X. Angles are
specified in radians. `sinh'(X) is defined as
(exp(X) - exp(-X))/2
`sinhf' is identical, save that it takes and returns `float' values.
RETURNS
The hyperbolic sine of X is returned.
When the correct result is too large to be representable (an
overflow), `sinh' returns `HUGE_VAL' with the appropriate sign, and
sets the global value `errno' to `ERANGE'.
You can modify error handling for these functions with `matherr'.
PORTABILITY
`sinh' is ANSI C. `sinhf' is an extension.
