Developer fixes number-to-words converter to handle up to 36-digit integers accurately
A developer discovered their number-to-words converter was silently producing wrong results for large numbers because JavaScript's floating-point system loses precision beyond 9 quadrillion. The fix involved treating the entire integer as a string throughout, splitting it into groups of three digits and naming each group using short-scale terms up to decillion, capping support at 36 digits. Decimal values are also handled character by character to avoid float rounding errors, which previously caused off-by-one-cent mistakes in currency conversions. The updated engine supports multiple currency modes, US and UK phrasing styles, and smart input parsing that accepts formats like $1,234.56 or European-style 1.234,56. Inputs containing letters or ambiguous formats are rejected with an error rather than silently misread.
