asinh, asinhf, asinhl - inverse hyperbolic sine function

Theasinh() function calculates the inverse hyperbolic sine ofx; that is the value whose hyperbolic sine isx.

On success, these functions return the inverse hyperbolic sine ofx. Ifxis a NaN, a NaN is returned. Ifxis +0 (-0), +0 (-0) is returned. Ifxis positive infinity (negative infinity), positive infinity (negative infinity) is returned.

No errors occur.
