How to declare variables as long numbers or some other format that use all the decimals available?

[Gysbert_Wassenaar]

LET vMyVariable = num(3/371, '0.0000000000000000');

There are no data types in QV.

So you can't really control how many bits are used to store your numbers internally.

You can only change / control the text format of a value, e.g. number of decimals displayed, if that's what you are after.

So when I realize an operation how do I know if I'm using all the decimals? 'Cause I'm getting different results.

Not sure if I understand, could you give an example?

[Gysbert_Wassenaar]

Qlikview only knows IEEE 754 compliant floating point numbers. See this blog post: Rounding Errors

Comparing between doing the same operation in two different softwares I don't get the same result, and I was wondering if it was because of the decimals...

Is this still an open question?

If you want more help, I think you need to describe your issue a bit more detailed, i.e. give us some examples what you see and what you are expecting to see.

You would probably also need to provide full context, so uploading a small sample QVW would be best.

If there is no open question, please close this thread by selecting an answer as correct or set the status to 'assumed answered'.
