Previous Comments: ------------------------------------------------------------------------ [2004-10-29 16:47:06] wiesemann@php.net The german text on this page is the exact translation of the english text. floor((0.1 + 0.7) * 10) returns 7 as stated in the text. So the original bug reporter should tell us where and what exactly the problem is. ------------------------------------------------------------------------ [2004-08-06 18:26:41] dave@php.net Updating the summary so people can easily see it's a German doc problem. ------------------------------------------------------------------------ [2004-05-18 16:41:24] derick@php.net It's a bug in the german docs... ------------------------------------------------------------------------ [2004-05-18 16:37:44] nlopess@php.net Write in english, please! ------------------------------------------------------------------------ [2004-05-16 12:57:11] udo dot steinbach at ewetel dot net Description: ------------ My english is to bad, so in german. In /de/language.types.float.html heißt es > Das gründet sich auf die Tatsache, dass es unmöglich ist, manche Dezimal-Zahlen durch eine endliche Anzahl an Nachkomma-Stellen darzustellen Das ist zwar richtig, aber die falsche Erklärung für den Satz davor > So wird floor((0.1 + 0.7) * 10) normalerweise 7 Siehe news:m3wvqvu656.fsf@penguin.slac.stanford.edu und news:3848a517.19666898@news.btx.dtag.de > Die Basis 10 ist inkommensurabelk mit der Basis 2. Auf binaer arbeitenden Gleitkommahardwares wird daher (change - dollar_amount) = 1/10 auf der Hardware nicht exakt darstellbar sein, sondern so etwas wie 0.0999… sein. Damit ist int(100*...)=9.
