numerica

Get the name of a number, even if it’s stupidly big.

References

• How high can you count?

Features

• Stringify/parse numbers and names in American/British short count (e.g. “million”, “billion”, “trillion”), or European (e.g. “million”, “milliard”, “billion”, “billiard”, “trillion”, “trilliard”).
• Support for exponential notation, even if in non-standard form (e.g. 123.45e+5).
• Support for negative numbers.

See TODO.md for a list of features that are planned for implementation.

Limitations

• Can only stringify and parse numbers and names that resolve to integer values.
• Exponents x in values are limited to Number.MAX_SAFE_INTEGER >~ x >~ Number.MIN_SAFE_INTEGER. Values may exceed extremes such as Number.MAX_SAFE_INTEGER and Number.EPSILON in which loss of precision may occur.
• No support for arbitrary number names such as “googol”.
• No support for fractional number names such as “half”, “quarter”, “third”, “tenth”, etc.
• Supports only native types (bigint, string, number).
