So I have a number that is 30 numbers long, but I get this as the output 1.0311510410510112e+29
And while mathematically that is fine, if I try to display it in on a Label, or use List Each it will output the letters as well which is incorrect.

I am able to add it to a Number List even a Number behavior even though letters are included.

What in the world are you calculating that requires a 30 digit integer?

If this is some sort of string formatting, then you might want to consider just using text types. If these are used for calculation, you might want to consider staying at or below the maximum safe (accurate) integer values for Javascript:
