|SINH(3)||Linux Programmer's Manual||SINH(3)|
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)):
sinh(x) = (exp(x) - exp(-x)) / 2
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.
If the result overflows, a range error occurs, and the functions return HUGE_VAL, HUGE_VALF, or HUGE_VALL, respectively, with the same sign as x.
The following errors can occur:
- Range error: result overflow
- errno is set to ERANGE. An overflow floating-point exception (FE_OVERFLOW) is raised.

The variant returning double also conforms to SVr4, 4.3BSD, C89.
