Handling big numbers

[yellow1912]

Omnipay, when dealing with numbers, should not use the normal methods. It should use either BCMath or GMP

Certain low value currencies such as the Vietnam's Dong can quickly get above the total number of digits that a 32 bit PHP system can handle and thus result in very very weird errors.

Omnipay should either:

1. Allow developers to override ALL these methods when necessary
2. Use one of those above libs to handle big numbers
3. Avoid getting dirty dealing with the currency amount and do not assume the amount to be integer or float.

It looks like an edge-case to me. I mean, how many servers are still on 32 bit systems?
