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;
 }
