It's more likely that the lengths are different, but only at the 12th or 16th decimal, which you can't see when looking at numbers via a panel.

Alright ..

Do you think rounding the length values will solve the issue ?

Thanks David

rounding could be a solution. Better is to build the difference of the 2 curve lengths and check agaist a tolerance value. This can be easy done with c#.

You don't need C# to ignore small differences when testing for equality:

Hi Ibrahim, you could use the Similarity component (in Maths > Operators tab)
