Congratulations, you've discovered floating-point arithmetic! Yes, sometimes doing math with non-integer numbers produces values that are slightly different than what you may expect. No, this is not a bug with PHP but actually a common issue with virtually every programming language.
Check that your precision and/or serialize_precision settings are set to -1 - or at least are set to reasonable values according to your needs. You also can round your results to an appropriate number of decimal places, remembering to do that only at the end of your calculations and never in the middle of them. Finally, if neither of those solutions works for you because of some very specific and unusual circumstances, arbitrary-precision math using BC or GMP is available.
