TOPIC:

LOCAL nDec AS System.Double oppure AS FLOAT oppure AS System.Decimal

nDec := (56/39)

torna sempre 1 e non 1,43.... grazie

Danilo

maybe my attempt will help

LOCAL nDec as Decimal

nDec:=(57./36.)

return 1.46

Juraj

Works, if you write either number with a ".0"
But this is certainly a bug

Ciao Danilo,

Juraj is right.

"57" e "39" sono considerati tipo integer, perciò il risultato sarà int, se non imposti /vo12 ("Integer divisions return float").

Altra possibilità:
Vedi: docs.xsharp.it/doku.php?id=literals

just one with a dot (57./39) or (57/39.) return 1.46

Hi Karl,

this is not a bug. If the /vo12 compiler option is not selected, every division by integers return an integer.
VO behaves the same.

Wolfgang,
i see. Hadn't thought that this may be the case even in core

And, as i just found out, it does not. Setting /vo12 makes the compile fail.
For reference tried in c#, the results are the same. So, it's one of these pitfalls, one has to keep in mind....
I think, i'd prefer the opposite behaviour as default, as i can't think of a lot of showcases, where one works on literal ints and wants to get the truncated result. But that's just me

funny, i firstly thought my cpu is defect, until i´ve noticed that there are different division that cause of course different results

(56/39)
(57./36.)
(57./39)

here´s another float result option

? (decimal) 56/39
? (double) 56/39
? (FLOAT) 56/39

Karl-Heinz

Thanks to all

so the behaviour of C# is the same as VO and X#.... I would also prefer to have the same as default - had similar problems several times in my VO applications, and therefore I'm always writing numeric literals with decimal point and 0 when dividing, and casting integer variables to float.

But compatibility is important, and changing it would break really a lot of code.

And I can understand why /vo12 makes the compile fail on Core dialect: there is no float datatype.
