Design a set of mathematical test cases for the number scalar types

1. Keep an eye out for overflow, other invariants.
2. Makes sure that the nubmers get ported to their idiomatic equivilants.

General flow:

Operation, LHS, RHS. (Strings)

ScalarType.unmarshal LHS (OPERATION) ScalarType.unmarshal RHS => RESULT

Send result up and validate result. Expect certain things.
