increasing the bank capacity

[omareco14]

since the bank can only keep 2,147,483,647$ (the maximum positive value for a 32-bit signed binary integer)
it seems you store the value in an integer variable in your databases
why not store it in an array?

MySQL 5.7 now provides a JSON data type. This new datatype provides a convenient new way to store complex data: lists, dictionaries, etc.

and when any item in the array gets to its max (2B) it just fills the next item
so the value would be the sums of all items in the array

By Reading the Thread, I think You are programmer, Well I don't have much knowledge About MySQL, But Money is useless in GamerX there is no need of Money. You can Only Use it, As /healme or Hitting yourself. So there is no need of Converting Binary to Array. Why not Sting.

Var1[Max_Lenght]= %s%

Or Whatever Just Kidding not Much Knowledge About it, Currently Learning C.

a string would be even easier
I only thought of that just because why not

your post looks more like a SA-MP forum post, i have been playing from years and still i have never been able to collect 2 billion, seems kinda worthless to work on.
