Precision #14

We're using high precision real variables for most arrays. However, is there an issue with ODE calculations where a high rate of change term results in later terms being rounded off as the are added?

I think this issue was resolved by capping all numbers are ~1e-30? Correct me and reopen the issue if I am wrong.
