Incorrect return value range for Math.Asinh/MathF.Asinh

[dstftw]

Return value doc is incorrect:

An angle, θ, measured in radians, such that -∞ < θ ≤ -1, or 1 ≤ θ < ∞.

Range of asinh function is -∞ < θ < ∞ not -∞ < θ ≤ -1, or 1 ≤ θ < ∞ (see image).

Here is a proof of Math.Asinh/MathF.Asinh actually returning θ values from range -1 < θ < 1 that is excluded from the current doc.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.
