Compute hyperbolic sine
Returns the hyperbolic sine of x.

Header <tgmath.h> provides a type-generic macro version of this function.
This function is overloaded in <complex> and <valarray> (see complex sinh and valarray sinh).
Additional overloads are provided in this header (<cmath>) for the integral types: These overloads effectively cast x to a double before calculations (defined for T being any integral type).

This function is also overloaded in <complex> and <valarray> (see complex sinh and valarray sinh).

Parameters

x
Value representing a hyperbolic angle.

Return Value

Hyperbolic sine of x.
If the magnitude of the result is too large to be represented by a value of the return type, the function returns HUGE_VAL (or HUGE_VALF or HUGE_VALL) with the proper sign, and an overflow range error occurs:

If an overflow range error occurs, the global variable errno is set to ERANGE.
If an overflow range error occurs:
- And math_errhandling has MATH_ERRNO set: the global variable errno is set to ERANGE.
- And math_errhandling has MATH_ERREXCEPT set: FE_OVERFLOW is raised.

/* sinh example */ #include <stdio.h> /* printf */ #include <math.h> /* sinh, log */ int main () { double param, result; param = log(2.0); result = sinh (param); printf ("The hyperbolic sine of %f is %f.\n", param, result ); return 0; }

Output:
 The hyperbolic sine of 0.693147 is 0.750000.
