Calculates the inverse hyperbolic sine of x.
Mathematically,
asinh(x) = log( x + sqrt( x*x + 1 )) // if x >= +0 asinh(x) = -log(-x + sqrt( x*x + 1 )) // if x <= -0
assert(isIdentical(asinh(0.0), 0.0)); assert(isIdentical(asinh(-0.0), -0.0)); assert(asinh(real.infinity) == real.infinity); assert(asinh(-real.infinity) == -real.infinity); assert(isNaN(asinh(real.nan)));
