function
sinh
<cmath>
double sinh ( double x );
float sinh ( float x );
long double sinh ( long double x );
Compute hyperbolic sine
Returns the hyperbolic sine of
x.
In C++, this function is overloaded in
<complex> and
<valarray> (see
complex sinh and
valarray sinh).
Parameters
- x
- Floating point value.
Return Value
Hyperbolic sine of
x.
If the the magnitude of the result is so large that it cannot be represented in an object of the return type, the function returns
HUGE_VAL with the same sign as the correct value of the operation, and the value of the global variable
errno is set to the
ERANGE value.
Portability
In C, only the
double version of this function exists with this name.
Example
1 2 3 4 5 6 7 8 9 10 11 12

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

Output:
The hyperbolic sine of 0.693147 is 0.750000.
