public static native double sinh (double x)

Returns the hyperbolic sine of a double value. The hyperbolic sine of x is defined to be (e^x - e^-x)/2 where e is Euler's number.

Special cases:

• If the argument is NaN, then the result is NaN.
• If the argument is infinite, then the result is an infinity with the same sign as the argument.
• If the argument is zero, then the result is a zero with the same sign as the argument.

Parameters:

x

The number whose hyperbolic sine is to be returned.

Returns:  The hyperbolic sine of x.

Since:  1.5
