NAMEsinh, sinhf, sinhl - hyperbolic sine function
#include <math.h> double sinh(double x);
float sinhf(float x);
long double sinhl(long double x);
Link with -lm.
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
DESCRIPTIONThe sinh() function returns the hyperbolic sine of x, which is defined mathematically as:
sinh(x) = (exp(x) - exp(-x)) / 2
RETURN VALUEOn success, these functions return the hyperbolic sine of x.
If x is a NaN, a NaN is returned.
If x is +0 (-0), +0 (-0) is returned.
If x is positive infinity (negative infinity), positive infinity (negative infinity) is returned.
ERRORSSee math_error(7) for information on how to determine whether an error has occurred when calling these functions.
The following errors can occur:
- Range error: result overflow
- errno is set to ERANGE. An overflow floating-point exception (FE_OVERFLOW) is raised.
CONFORMING TOC99, POSIX.1-2001. The variant returning double also conforms to SVr4, 4.3BSD, C89.
