0.1 + 0.2 is not 0.3 in JavaScript.
That's because every number in JavaScript is represented using 64 bits floating point. Since numbers are saved in binary, there are some decimal numbers that are periodics in binary but not in decimal, e.g. 0.2, equivalent to 0.00110011001100110011... in bin. You can avoid this using some BigDecimals libraries like decimal.js, or, if you need to work in different bases, you have Basenumber.js

Numeric from DB to string.
So yeah, there's no zero effort drop-in replacement. If you really really need all that precision (which I doubt), I'd recommend using something like js-big-decimal to handle the heavy lifting.
