PointAtNormalizedLength (C#) vs. PointOnCrv (GH)

Hello,

Why does the PointOnCrv component from Grasshopper give me a different point than the PointAtNormalizedLength method in C#, even though I used the same curve and parameter?

This was the code I used:

Point3d pt = new Point3d();

pt = crv.PointAtNormalizedLength(t);

A = pt;

Cheers,

Max

The PointOnCurve slider may actually have additional digits it does not show. I'm not entirely sure. If you zoom in on the PointOnCurve slider and drag it just a little bit, can you move the point without changing the value to 0.61 or 0.63?

Ah, indeed I can, good to know!

Is that a mistake or is there a particular reason?

I can't remember. It sounds like a mistake now.
