On 4/12/98 4:03 PM, Akuma/Chris Baggett/DOOMer (doomer18@EARTHLINK.NET) stated: >int top_of_dam_messt = 18; >int perc_hit = 6; > > msgnum = (int)(((perc_hit)/(top_of_dam_messt + 1)) + 0.5); This is because ints drop decimals, regardless. For example: (value / max) will always be 0, since VALUE is less than Max. (value / max) * 100, for calculating a percentage, will always be 0 also, because 0 * 100 = 0. The proper method for determining a percentage value is: (value * 100) / max = % So, applying basic substition algebra (substition? I think that is the property being used :-), assuming you have the percentage, and want to find what the index would be: (percentage * max) / 100 = index 6 * 18 = 108 108 / 100 = 1.08 (drops .08) So if you have 100%, it is: 1800 / 100 = 18 50 * 18 = 900 900 / 100 = 9 Subtract 1, and you have the index from your dam_message table. If the table is the count, rather than the index of the top entry (which is not the standard circle method), use (top - 1) This formula was reached in the following manner: (value / max) * 100 = percent percent / 100 = value / max percent / 100 * max = value percent * max / 100 = value (remember, order of applying divisions and multiplications is unimportant when only divs/mults are present! This order also preserves divisions for a later time, when values will be largest and risk of dropping decimals is lowest, and least important). - Chris Jacobson +------------------------------------------------------------+ | Ensure that you have read the CircleMUD Mailing List FAQ: | | http://democracy.queensu.ca/~fletcher/Circle/list-faq.html | +------------------------------------------------------------+
