it gives false although it is true… the equality component behave strangly!

My best guess from the screenshot is that it’s a rounding error issue- measuring curve length won’t return you a exact whole number 5 even though the panel displays it as 5, it’s probably 5.000000000736 or something due to floating point precision.

You should be converting both numbers to integers if doing integer comparison, or else taking the difference between the numbers and checking if that is below a certain tolerance.

you are right that was the problem, thank you

Also check out Pufferfish plugin, there’s a component called “Equality within tolerance” that makes it easy to avoid these kinds of mistakes :slight_smile:
