Yet another way, based on a logarithm method by Smurfier back in the day (too lazy to search for its forum link at this hour):Scale (any) and Decimals (up to 3, since the 4th and 5th are used to store the unit as a decimal before conversion to k, M, G and so on) are variables just in case some "parameters" are desired, otherwise they can be hardcoded in the formula. This might work for negative values too, though not 100% sure, as I just copy pasted it from my skins.
