Question

I have a crazy effect when displaying in view with a number column in a dynamic view panel of an xPage:
Some (not all!) entries are displayed like:
123.40000000000005

the value in the notes doc is 123.4 .

I cannot found any difference between that wrong displayed value and others, which are displayed correctly.
I tried a few number formatting things in the column properties of the notes view: does not improve.

the notes view displayed everything well (for the notes client).

Is it a bug? Or did a forget some format settings for the dyn view control?

Thanks in advance, Uwe

Its not a bug, more like a side effect.

Well because it is double, there is way to put floating point numbers in memory, sometimes it behaves “little bit strange” but its just a side effect. So there is sometimes small error in numbers.

read this: http://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html
it explains how floating point works.
