sinh - hyperbolic sine function
#include <math.h> double sinh(double x);
The sinh() function computes the hyperbolic sine of x.
An application wishing to check for error situations should set errno to 0 before calling sinh(). If errno is non-zero on return, or the return value is NaN, an error has occurred.
Upon successful completion, sinh() returns the hyperbolic sine of x.
If the result would cause an overflow, ±HUGE_VAL is returned and errno is set to [ERANGE].
If the result would cause underflow, 0.0 is returned and errno may be set to [ERANGE].
If x is NaN, NaN is returned and errno may be set to [EDOM].
The sinh() function will fail if:
- The result would cause overflow.
The sinh() function may fail if:
- The value of x is NaN.
- The result would cause underflow.
No other errors will occur.
