Oracle Number type not displayed correctly in Qlik sense

[brichnma]

Dear,

I have numbers in my oracle DB (example 0,1,10,4, 0.5, etc.). The field is "HOLARIS # Days".

When I upload the data to my Qlik sense, I don't always have the same values. Usually it is 6 instead of 7, or 9 instead of 10,  or 1 instead of 0, etc. But for other values I have the right result, so 10 is shown as 10, 9 is displayed as 9..

I really don't understand and see where is the problem and how to fix it.

Can some one help me please?

Many thanks
