Using mathjs as a more advanced alternative the the corejs Math Object
When it comes to doing anything with math in javaScript there is of course the corejs Math object that is very helpful, but it does have it’s limitations, and does not always work the way I would like it to. A popular alternative to the corejs Math object is math.js, which can be found on npm, and github like most projects. It can do everything the Math object can, as well add a whole bunch of new features such as big number support. In addition certain mathjs equivalents to the Math object methods have additional features, and also a plug in system exists that can be used to further extend mathjs.
Installing
Mathjs can be used as a front end solution, as well as in node.js. In anode.js environment just install with npm like always.


In this post I am using mathjs 4.x, and I assume a node.js environment.
using mathjs in place of the Math Object
I tend to favor using mathjs separately as an alternative to the Math Object in core javaScript, rather than monkey patching the Math Object. This means I will have two globals, one lower case, and one upper.
Plug in system
mathjs has a plug in system, and there are additional projects that wok well with mathjs when it comes to getting into a certain discipline involving math. Of course it is not that hard to add my own functionality as well if I cant fine something.
The natural logarithm method
For starters I checked out the mathjs natural logarithm method, and have found that it is an improved alternative over the native Math.log method as it can also be used to find base log.
The improvement has to do with base log


With math.js I can just give a second argument


If you are still wondering what base log is, just think of it as the opposite of using Math.pow. Where I want to find an unknown exponent given a number and base, rater than finding an unknown number given a base, and exponent.
