asinh - Inverse hyperbolic sine
float asinh( float $x )
asinh() calculates the inverse hyperbolic sine of x, i.e. the value whose hyperbolic sine is *x.
x - The number to process. It can be a scalar or an array.
The inverse hyperbolic sine of x. If x is an array, then the return value will also be an array.
