[C4D] Round a value to the nearest grid point

/// This is an extended version of Round(), rounding not just to the nearest whole number but to the nearest point in a grid with arbitrary spacing.
/// Using "1.0" as value for grid will give the same results as Round().
///
/// @param[in] value The input value
/// @param[in] grid The grid spacing
/// @return The rounded value
