How to increment a 4 decimal place value in Javascript?

Question

How do you increment a currency fractional part?

For instance, let's say you have 14.0009 and you want to increment it to 14.0010 when press the up arrow key

I'm afraid it's not clear what you're asking. On the face of it, you just add `0.0001` to the number. Have you had some problem doing that? (For instance, [this one](https://stackoverflow.com/questions/588004/is-floating-point-math-broken)?) If so, you may need a "big decimal" library. (A native one may be coming to JavaScript at some point, but not in the next couple of years.) — T.J. Crowder, Sep 03 '20 at 14:23

If you are using a HTML5 Input number field then set the step attribute to step="0.0001".
