hello list !
i have got a little problem... i try to format numbers as they may represent 4 integers with the following "decimal scheme" : a.bccdd so that 1.23456 becomes the list 1 2 34 56. i thougth this could be useful to store formatted-lists in arrays (maybe saw it's easier with data-structures or simply using multiple arrays). but what i don't understand is that, sometimes, i don't get the exact number in the latest decimals : instead of getting 56 i have 55.99985 or 56.00021 or something like that. is it bug from [int] or is it because of "32-bit floating point" format ? i've joined a patch to show the problem. i've tried many different ways but none of them worked. is it normal, have you got an idea ?
thank you
raphaël

Hello Raphaël, Look at this patch for the solution with your patch.
Look explanation of Frank and Tim : http://lists.puredata.info/pipermail/pd-list/2006-03/036698.html http://lists.puredata.info/pipermail/pd-list/2006-03/036668.html
exemple : 1.4 - [int 1.4] != 0.4 (NOT GOOD) but : ((1.4*10) - ([int 1.4]*10))/10 == 0.4 (GOOD)
