Installation
$ composer require backendtea/safe-bc-math
Why this package
Casting a float to a string does not always do what you think it does.
Some locales may give unexpected results, and give a malformed string, or
the number is cast to a scientific notationm for example: 1.0E-11
. Which bcmath cant handle.
Even if you do not manually cast it to a string, the bc math functions expect strings, and will cast it themselves.
This package will throw an exception telling you what error it encountered, instead of giving a
warning bcmath function argument is not well-formed
and returning a wrong error.
Usage
Replace any usage of bc math functions with the Backendtea\bc..
version.
e.g.
- bcadd($a, $b); + \BackEndTea\bcadd($a, $b);
Or even better, import the funtion:
+ use function BackEndTea\bcadd;
bcadd($a, $b);
