This page will discuss how EMC is stored in the mod.

Infinite precision

Every EMC value in Fabricated Exchange is stored as two BigIntegers which are treated as a numerator and denominator representing the value. BigInteger is a Java class that can represent an integer of arbitrary size, and with two of them, you can represent any real number that isn't irrational with enough RAM. The reason I chose to do this is to solve two problems that every previous iterations of the mod had:

1. EMC was bound with some limit, either (2^32)/2 or (2^64)/2.
2. Items like Stone slab could not have EMC, as it was below 1.

Doing it like this fixes both.

Performance Concerns

I have yet to run into performance issues due to the added overhead of the new number class. If they arise, there are potential solutions, such as switching to a faster alternative to BigInteger, or possibly switching to long which would unfix problem 1, but would likely increase performance by a lot.
