C# float? rounding issue with "long" numbers

Hi,

I have an Editor field defined in C# as float?. In JS I defined the field and the columns without any particular setting.

If I save, for instance, the value 10.12345, everything is fine, i.e. the value is correctly saved in the DB and is correctly re-loaded.

But if I save, for instance, the value 1000.12345, there are issues:
* in the DB the value saved is 1000.123
* the re-loaded value is 1000.12347

With 10000.12345:
* in the DB the value saved is 10000.12
* the re-loaded value is 10000.123

and so on...

So first of all it seems that the maximum length for a number saved in the DB is 8 (with the dot), e.g. 10000.12

Moreover it seems that there are also issue when the value is reloaded from the DB.

Can you please clarify?

Thanks!
