SINH(3) Library Functions Manual SINH(3)

sinh, sinhf, sinhlhyperbolic sine functions

#include <math.h>

double
sinh(double x);

float
sinhf(float x);

long double
sinhl(long double x);

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

The sinh(), sinhf() and sinhl() 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.

The sinh() function conforms to ANSI X3.159-1989 (“ANSI C89”).

The sinh() function first appeared in Version 7 AT&T UNIX.
