{{alias}}( x, n, b )
    Rounds a numeric value to the nearest multiple of `b^n` on a linear scale.

    Due to floating-point rounding error, rounding may not be exact.

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

    n: integer
        Integer power.

    b: integer
        Base.

    Returns
    -------
    y: number
        Rounded value.

    Examples
    --------
    // Round to 2 decimal places:
    > var y = {{alias}}( 3.14159, -2, 10 )
    3.14

    // If `n = 0` or `b = 1`, standard round behavior:
    > y = {{alias}}( 3.14159, 0, 2 )
    3.0

    // Round to nearest multiple of two:
    > y = {{alias}}( 5.0, 1, 2 )
    6.0
