[Gambas-user] How to handle unsigned Integer, Short, Long

[wally]

Hello

@Jussi,

i must handle a lot of 4byte uint32_t values which represents
node IP addresses of devices in a rs232 ring network.
I know i might use long instead of unsigned 4byte integer,
but i expected there is a keyword "unsigned" somewhere to
declare as needed.
The "long" approach for uint32_t is not very elegant solution.

So answer seems to be, Gambas3 does not allow to declare
unsigned variables as there are e.g. : uint32_t andd friends.

Is this correct so far ?    <-- seems yes, as Benoit wrote.

@Benoit:

Alas you have no unsigned datatypes in Gambas. Maybe in a future Gambas 4?

You have to use signed version, and be careful with the arithmetic you
are doing.


If it is not too much work it would be nice to have unsigned in version 4.
Yes, exactly, the maths is the problem. In c i get overflow warnings at 
lest.
