sinh, 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)): sinhf(), sinhl(): _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L || /* Since glibc 2.19: */ _DEFAULT_SOURCE || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
These functions return the hyperbolic sine of x, which is defined mathematically as: sinh(x) = (exp(x) - exp(-x)) / 2
On 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. 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.
See 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.
