It seems like bignumber#sub: is crashing. Apart from this, do you think adding this library to benchmarks will provide any value? It doesn't seem like any of covered functions are faster in bignumber.

Thankfully it is not anywhere near to bn.js. I have a couple of projects I would like to convince to switch to bn.js form bignumber and having benchmarks certainly helps.

Didin't notice .sub not working, strange.

@indutny rebased against master and fixed .sub. All the methods in bignumber.js are faster than silentmatt-biginteger.

Ah, closing this :)

To the defend the point of this, here's a comparison of github stars, npm dependents and npm downloads last month of each of the bignum libraries used currently in benchmarks:

• bignum (node-bignum), 211 stars, 49 deps, 51,687 downloads
• sjcl (eccjs), 41 stars, 5 deps, 86 downloads
• bigi 8 stars, 39 deps, 6171 downloads
• js-big-integer 10 stars, 9 deps, 50 downloads
• biginteger 133 stars, 2 deps, 93 downloads

How bignumber compares:

• bignumber.js 667 stars, >50 deps, 333,311 downloads

Note: the package sjcl should be used instead of eccjs as it is more up to date and has more users: 3113 stars, 42 deps, 5396 downloads

My points is that benchmarks should be made against:
a) better performing libraries;
b) widely used libraries.

Alright, let's throw away biginteger then, and replace it with bignumber.js.

Also good point about sjcl.
