Strange rounding in the calculation result in "Parameters" (OpenLCA 2.0.3)

Question

Dear OpenLCA team,

In OpenLCA v2.0.3, in the "Parameters" tab, I have an incorrect sum result (please see screenshots). It either adds or suppress a 0.0000000001 to the total result :)

Not a big issue but pretty surprising. Have you got any idea of the source?

And many thanks for this amazing tool!

Hi thierry.l,

This is typical for computers to be sometimes a little bit wrong due to floating point math. Please have a look at a good explanation over there: https://0.30000000000000004.com/
