Bug #17787 Updated: integer/double problem

ID: 17787 Updated by: j.neubert@21torr.com Reported By: j.neubert@21torr.com Status: Bogus Bug Type: Math related Operating System: Windows NT 5.0 build 2195 PHP Version: 4.1.2 New Comment: Derick, the explanation on http://www.php.net/manual/en/language.types.float.php#language.types.float seems to be pretty lame excuse for not being able or willing to check for a c-math-lib on the corrosponding system to be able to do such simple mathematic equations transparent to the user... you have to admit that this could be very well regarded as a bug or a not very well documented feature... true, binary equations are a hastle to do, but with all of the things php does for you, this shouldn't be to much of a hastle for the php-developers... In the end it _IS_ an expected behaviour that 2.26 multiplied with 100 equals to 226, binary equation or not, statet in an obscure place in the documentation or not... anyhow, have a nice day too and thanks for your quick reply.
