{{alias}}( x )
    Evaluates the error function.

    If provided `NaN`, the function returns `NaN`.

    As the error function is an odd function (i.e., `erf(-x) == -erf(x)`), if
    provided `-0`, the function returns `-0`.

    Parameters
    ----------
    x: number
        Input value.

    Returns
    -------
    y: number
        Function value.

    Examples
    --------
    > var y = {{alias}}( 2.0 )
    ~0.9953
    > y = {{alias}}( -1.0 )
    ~-0.8427
    > y = {{alias}}( -0.0 )
    -0.0
    > y = {{alias}}( NaN )
    NaN
