hugenumberjs

A library for storing extremely large numbers (up to {10, 1000, 1, 1, 2}) in JavaScript. Supports both Node and browser.

Internally, number is represented as a sign (1 if positive, -1 if negative) and array. The value represented is sign * 10 → array[0] → array[1] → array[2] → array[2]... in chained arrow notation (specifically Fish's real number extension of it).
