Numerical rule choices
Specify caps, bands, indivisible allocation, valid increments and signed results.
Choose whether an excess value is capped or rejected
Separate limiting a calculated result from refusing an input.
Apply bands to portions rather than the whole quantity
Contrast marginal and whole-quantity calculations with exact inputs.
Allocate whole units from proportional shares
State a remainder rule instead of rounding each share independently.
Specify allowed increments as well as a numeric range
Describe the valid value grid rather than accepting every value between endpoints.
Keep a signed difference separate from a nonnegative remainder
Choose the intended mathematical output before hiding negative values.
