This is great! Proper support for this has been lacking in the Node world. I recommend json-bignum [1] if you need a Node library for JSON serialization that can handle large numbers. For example, retrieving a JSON-formatted row from Postgres which has int64 or numeric values. It is slower than the native JSON functions though.

Disclaimer: I wrote json-bignum.

Hoping somebody could explain to me why methods are written like so:

P['absoluteValue'] = P['abs'] = function () { }

instead of

P.absoluteValue = p.abs = function () {}

Indeed. And, interestingly, Decimal.format (alone?) is declared with dot notation[0]. Overall coding style feels relatively consistent so there must be some reasoning behind these decisions.

Reading the ReadMe.md makes me wish that javascript let you overload / implement operators.

Type looks cool though
