Prototype
double sinh(double x);
long double sinhl(long double x);
Description
Calculates hyperbolic sine.
sinh computes the hyperbolic sine.
sinl is the long double version; it takes a long double argument and returns a long double result. Error handling for sinh and sinhl can be modified through the functions _matherr and _matherrl.
Return Value
sinh and sinhl return the hyperbolic sine of x.
When the correct value overflows, these functions return the value HUGE_VAL (sinh) or _LHUGE_VAL (sinhl) of appropriate sign. Also, the global variable errno is set to ERANGE.
Example
#include <stdio.h> #include <math.h> int main(void) { double result, x = 0.5; result = sinh(x); printf("The hyperbolic sin of %lf is %lf\n", x, result); return 0; }
