# SYNOPSIS

`#include <math.h>`

double
`sinh`(double x);

float
`sinhf`(float x);

# DESCRIPTION

The `sinh`() function computes the hyperbolic sine of x.

# RETURN VALUES

The `sinh`() function returns the hyperbolic sine value unless the magnitude of x is too large; in this event, the global variable errno is set to `ERANGE`.

# SEE ALSO
