too big for int [message #1299853]

Hi,

I need to process a numeric string which is too big to fit in an int.
A value which fails:

4294967295

This is actually the exact max size of an unsigned int, but java int is
32bit signed, so this won't fix. So I guess I need a unsigned int here.

I tried changing the return type to EBigDecimal and EBigInteger but I
still get errors/markers in the editor.

terminal INT returns ecore::EInt:
'-'? ('0'..'9')+;

Do I need to implement an IValueConverter or is there a way to handle
this in the grammar directly.?

Thank You,
Christophe

Christophe,

Did you mean to post this to the TMF forum? ELong might be enough...
