bigDecimal.add is not a function(there is a "default" field)

[SilentFlute]

this pkg is great, and light weight, i like it, but when i trying to use it, i got some troubles...

i add js-big-decimal with this cmd:
$ yarn add js-big-decimal
and create a js file: foo.js, and typed these codes in it:

const bigDecimal = require('js-big-decimal');

console.log(bigDecimal.add('12', '45'));

and then i did this:
$ node foo.js
as least, i got this:
bigDecimal.add is not a function

then i did some debug things, i figured out: there is a 'default' filed, so i changed the code like this:

const bigDecimal = require('js-big-decimal');

console.log(bigDecimal.default.add('12', '45'));

then it went will

but the doc didn't mention that, am i did a wrong way or sth? and what's the 'default' field used for?

This should not be happening. Looks like some bundling. Will have to take a look. For the time being, you can use 1.4 based versions. Those will not have this issue.
