Maximum & minimum supported number overflow

[dakota-kallas]

Describe the bug
This bug is related to the core functionality of the plugin. JavaScript supports up to a maximum integer value of 2^53. I want to use the numeric mask, but am running into cases where I am exceeding this limit. The plugin is casting my values down or up to the maximum or minimum safe integer supported by JS. This is preventing me from being able to use the numeric mask. It would be nice if this used something like a BigNumber type or was done using string manipulation of some kind so that it would support more than the maximum and minimum number values or a poly fill of a bigger type.

The plugin is expecting a number type for both min and max when using a numeric mask. This is a part of the problem.

hi, i don't think it's a problem. Number mask works with number type. That's fine.
If you need more then you can try function mask or use combo regexp + validation. No big deal. IMask has a good start for any custom solution.

Do you have any suggestions, @uNmAnNeR, as to how I would go about creating a mask that works identical to a number mask, just supporting a number larger than 2^53?

Okay, i have a suggestions.
Start with something like https://codepen.io/uNmAnNeR/pen/yLQbvYy?editors=1010
may be it already solves your problem.
if not: overwrite format/parse callbacks to handle string <-> YOUR-TYPE conversion
if still not: inspect sources for number mask, remove validation that you don't need and create your custom mask

Not quite the solution I was looking for, I ended up creating a fork to change how the numeric mask works. It changes the max and min values to be treated like string that allow you to set a maximum and minimum about of digits allowed before/after the decimal point (https://github.com/dakota-kallas/imaskjs). I couldn't find a way to use my forked repo as a dependency ( #892) properly with npm, so I had to change around the file structure a bit as well.
