NAME    [Toc]    [Back]

     sinh, sinhf -- hyperbolic sine function

LIBRARY    [Toc]    [Back]

     Math Library (libm, -lm)

SYNOPSIS    [Toc]    [Back]

     #include <math.h>

     double
     sinh(double x);

     float
     sinhf(float x);

DESCRIPTION    [Toc]    [Back]

     The sinh() and the sinhf() functions compute the hyperbolic sine of x.

RETURN VALUES    [Toc]    [Back]

     The sinh() and the 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.
