Hi Boki

Are you aware of the fact that the AsInteger method on NextGrid, NxNumberEdit, NxSpinEdit etc uses Round() to get the Integer value?

Example:
(3.4).AsInteger = 3
(3.5).AsInteger = 4

I would have expected (X).AsInteger = Trunc(X)

If this is by design then it is fine, as long as you are aware of it. It caught me by surprise

Regards,
Deon

Hello Deon,

I have made it like this. But, maybe a better will be to have property for setting RoundMode (lower, nearest...).

Where will this property be used?

If it is only used to round AsInteger then it is not really worth it to add a new property just for that.

I would suggest that you stick to the standard expected behaviour, and leave the rest up to the programmer. As far as I can remember the standard DB behaviour for AsInteger is Trunc(X).

If the programmer wants a rounded value he can still use Round(X.AsFloat), or RoundTo(X.AsFloat,-2) or Trunc(X.AsFloat) or whatever...

Hello Deon,

I think that this is expected behaviour. You may allways call SetRoundingMode before calling AsInteger. This function include rmTruncate as parameter too.

If that is the standard behaviour for AsInteger then it's fine. As long as I know what to expect I can code around it.

Hello Deon,

Calling Delphi's SetRoundingMode may give you big flexibility, better than only calling Trunc.

Best regards
