1.55 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.

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.
