{{alias}}( x )
Evaluates the inverse error function.
If `|x| > 1`, the function returns `NaN`.
If provided `NaN`, the function returns `NaN`.
As the inverse error function is an odd function (i.e., `erfinv(-x) ==
-erfinv(x)`), if provided `-0`, the function returns `-0`.
Parameters
----------
x: number
Input value.
Returns
-------
y: number
Function value.
Examples
--------
> var y = {{alias}}( 0.5 )
~0.4769
> y = {{alias}}( 0.8 )
~0.9062
> y = {{alias}}( 0.0 )
0.0
> y = {{alias}}( -0.0 )
-0.0
> y = {{alias}}( -1.0 )
-Infinity
> y = {{alias}}( 1.0 )
