Description:
------------
My english is to bad, so in german.

In /de/language.types.float.html hei?t es
> Das gr?ndet sich auf die Tatsache, dass es unm?glich ist, manche Dezimal-Zahlen durch eine endliche Anzahl an Nachkomma-Stellen darzustellen

Das ist zwar richtig, aber die falsche Erkl?rung f?r 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.

It's a bug in the german docs...

Updating the summary so people can easily see it's a German doc problem.

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.

The German team considers this bogus.
