min_signal is intended to optionally skip checking float
distances when numbers are close enough to 0.
Only skips when both numbers are < min_signal.
Intention is to allow tighter float testing in certain
cases where most values are not near 0, but values near
zero are differing by more bits than values farther from 0.
Should be used with caution in limited cases.
