Upper limit of data type Number (Integer) is 2,147,483,647. I've

Similar question if there is any solution / workaround is available :

------------
In our case, we have CDT which accepts Number data type (It can be integer/decimal) - so we have used floating point field which will allow decimals along with integer. Now when we add more than 7 digits, the value rounds off. While using integer fields which comes with a validation of total max length 2,147,483,647 ,it is converted to exponential.

We can't use text as Number is defined data type of CDT, and also we want to allow decimals, is there any way we can achieve this using floating point field?

Example:
Value used is 123456789
After entering, it's automatically rounded up to be 123456800
In Tempo, it shows 1.234568e 08
