Respected Eugene Bernard, The double negative is used to "coerce," as we say, a non-number type into a number type. Since only a number (not text, boolean, error value, etc.) can follow a minus sign, one minus sign forces the coercion to a number. The other just reverses the sign change caused by the first one.
