What Is Words to Number?

The Words to Number converter parses English number words and converts them to numeric values. It understands ones (one through nineteen), tens (twenty through ninety), hundreds, thousands, millions, billions, and trillions. It handles compound numbers like "forty-two", "one hundred and twenty-three", and "three million five hundred thousand". The word "and" is ignored as a connector. "Negative" or "minus" prefixes are supported.

Technical Guide

The parser normalizes input by lowercasing and removing non-alphabetic characters except spaces and hyphens. Hyphens are converted to spaces. The word "and" is filtered out. Words are matched against lookup tables for ones (0-19), tens (20-90), and scale words (hundred, thousand, million, billion, trillion). The algorithm accumulates a current value and a result. When a scale word is encountered, the current value is multiplied by the scale (for "hundred") or multiplied and added to the result (for thousand and above). The "negative" and "minus" prefix words set a flag for the final sign.
