Hi everyone, i’m reading data from 1 column of an excel file and write it to other column of another excel file. The problem is, the data i read from the original column is “0”, but the data written to the output file is 2E-15. I don’t know what happened. Could anyone help me with this please!
Here is the original data

It seems Floating-point arithmetic matter.
17:00 is 0.708333333333333 and 8:00 is 0.333333333333333 in Excel serial value.
And the result of the formula will be 1.77635683940025E-15 exactly.

Look at the source of those formulas, some of them have 0’s, some of them have more and more formulas. But that is really more of an Excel question than a UiPath question.

If you use the Excel activity, you should get the same Excel value. If you use the System activity, you will have to handle the rounding separately.
