QUESTION
I would like to find out whether one real number is a multitude of the other one. I'm using BC-Math because the code is part of a larger system doing price calculations and using floats results in wrong results on multiple calculations due to the behaviour of floating point math.
BC-Math has bcmod()
to get the modulus of an arbitrary precision number. However, before PHP 7.2 this function does not work with non-integer numeric strings. E.g:

Install bcmath-extended
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
