Need to pass Integer-value in .net

[MBaas]

I am trying to use a .net-Tool that requires Integer-Values in some params. When trying to assign an integer, I get a DOMAIN ERROR (in 10.1). That is because the argument is a small number ([]DR is 83). How can I make sure this gets passed as a 323-int?

dotnet.Function.IntVal <- System.Convert.ToInt32 var
:)

System.Convert.ToInt32 var will return APL numeric.

⎕DR Convert.ToInt32 0
83

But ToInt64 will return an instance. But Dyalog casting between APL and CLR for numeric values normally work OK for me. Can you provide with example?

We had similar issues with .NET in 10.1 and solved it by using

Code: Select all

(Int64.Parse,'123')

as the argument to a .NET method. I grepped through our code base and we have a couple of instances of Int64.Parse and one Int32.Parse, probably to work around issues like these.

I didn't write the code, but I vaguely remember the person that did talking about how the behaviour varied between different versions of Dyalog. It might not be necessary with newer versions.

My variable happened to be zero and the ToInt32-call fixed this. According to Azal this wouldn't be expected, but hey - after all, I'm happy enough that it did the job ;)

Joakim's code also looks good, thanks - if the homemade solution should fail once I work with numbers > 0, I will try that route ;)

Thanks

What about using dyadic ⎕dr?

0
0
⎕dr 0
83
to16 0
0
⎕dr to16 0
163
to32 0
0
⎕dr to32 0
323
⎕cr 'to16'
to16←{163=a←⎕DR ⍵:⍵
z b←(a 163)⎕DR ⍵
∧/b:z}

⎕cr 'to32'
to32←{323=a←⎕DR ⍵:⍵
z b←(a 323)⎕DR ⍵
∧/b:z}

Yes.....looks feasible too ;)

(embarrassing) truth to be told: I've never used dyadic DR. I actually tried to do so when looking at this prob, but didn't fully understand the doc, so the last thing I did was 323 DR 0 causing ERROR, and I then gave up on it, as I felt a certain pressure to get a result... :(

Yes.....looks feasible too ;)

Your .Net class is accept naive []DR conversion? Can you check it please?

[MBaas]

Yes, I just did a quick test with
t.IntegerValue←1⊃(83 323)⎕DR lmng
(after checking the ⎕DR of lmng was 83) and that was accepted...
