PHP4 cuts floats down to ints...

Hi everybody! We´re encountering strange problems when using PHP´s _basic_ math functions. It seems that PHP cuts every number to an integer, no matter what type it used to be. For example if we execute <?PHP echo (1.5 * 8.7 / 4.5); ?> the result is 2. Just if the interpreter calculated 1*8/4. This "error" doesn´t appear on our local environment where we use PHP3, but it occurs on our WebServer running PHP4. It doesn´t matter if we use native float numbers like in the example above or define strings like "1.9985". In the last case the string has the correct value. At the point the calculation is performed the number is cut down to 1. We believe that there is some wrong configuration option in our php.ini but can´t figure out what it may be. Maybe anyone can help us. Thanks in advance, Sascha Dahl bestEshop.de AG TechnologieZentrum Friedrich-Ebert-Str. 51429 Bergisch Gladbach e-mail: sdahl@besteshop.de
