NAME    [Toc]    [Back]

     sinh, sinhf - hyperbolic sine functions

SYNOPSIS    [Toc]    [Back]

     #include <math.h>

     double
     sinh(double x);

     float
     sinhf(float x);

DESCRIPTION    [Toc]    [Back]

     The sinh() function computes the hyperbolic sine of x.   The
sinhf() function
 is a single precision version of sinh().

RETURN VALUES    [Toc]    [Back]

     The  sinh() and sinhf() functions return the hyperbolic sine
value unless
     the magnitude of x is too large; in this event,  the  global
variable errno
     is set to ERANGE.
