{{alias}}( x )
    Relative error exponential.

    When `x` is near zero,

        e^x - 1

    can suffer catastrophic cancellation (i.e., significant loss of precision).
    This function avoids the loss of precision when `x` is near zero.

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

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

    Examples
    --------
    > var y = {{alias}}( 0.0 )
    1.0
    > y = {{alias}}( 1.0 )
    ~1.718
    > y = {{alias}}( -1.0 )
    ~0.632
    > y = {{alias}}( NaN )
    NaN
