startRuleEvaluation function

void startRuleEvaluation(
  1. num howMany,
  2. [int precision = 0]
)

This must be called before evaluating a new rule, because we're using library-global state to both keep the rules terse and minimize space.

Implementation

void startRuleEvaluation(num howMany, [int precision = 0]) {
  _n = howMany;
  _precision = precision;
  _i = _n.round();
  _updateVF(_n, _precision);
  _updateWT(_f, _v);
}
