Pasquale,

No.  In JS (the target of the compiler), a number is a number (there are some exceptions to this for bitwise operations, but they're irrelevant here and will only cause confusion).  Only in EWB is there a distinction between integers and doubles.

but iocome do I handle these numbers ?

You need to do control checks on these numbers that are entered as you can see from the code snippet I posted

You can't.  You're exceeding the capabilities of the runtime engine that you're using.

We don't control the JS runtime, the browser does.

If you need to actually work with them in EWB application then only way
i know how to deal with these is to treat all numbers as strings in EWB
and then use an external javascript big-int library (there are few
available - google for them).

In this case using an external library should be very straightforward
since you just need the library to do the calculations (i.e. no UI
involved).

Note that this is an issue with any Javascript application and not
unique to EWB.
