Grasshopper - Mirrored interpolation curve value inaccuracy

[Intuos]

Hi all,

Today I noticed that the distance value of mirrored interpolation curves differ from the distances I specified (by a 0,08 mm margin). This can be seen in the right most panel showing 5999.924 instead of 6000.

The values are supposed to read like this:

Previously, I used two nurbs curves with mirror, those did not show this deviation. I only found out this occurred when I changed the components to interpolate curves. This inaccuracy shouldn’t be happening, should it?

Your curve are curved, not straight, not parallel on XZ plane.
The points you evaluate (at 0 and 0.5) are correctly mirrored.
The first distance is correctly 6000, the second must be NOT 6000.

Everything is correct.

Your expectations are wrong, check again what you are doing.

Indeed, I overlooked that one. Nevermind.
