It's quite handy to have something like this:

(3/4*Math.cos(0)).should.be.approximately(0.75, 1e-2);

But at the moment I haven't found such possibility in should.js. So, since I like this library and don't want to switch to another one, please, accept these changes and merge them into master to be released (I hope) soon.

Documentation should be added for this.
