Split a money amount into shares without losing or inventing a cent
Split a money amount into shares without losing or inventing a cent. Divide evenly into N parts, or by a list of ratios, and the remainder is distributed one minor unit at a time by a named, deterministic rule — largest-remainder, first-wins or last-wins — so the parts always sum exactly to the original. Uses Unicode CLDR minor-unit digits, so zero- and three-decimal currencies work (CLDR differs from ISO 4217 for a few, e.g. IDR, HUF: 0).
