Gcode expression.gh (9.5 KB)

as the picture doesnt work:
Capture

My Evalues are changing in the output!
what did i do wrong in the expression.

Im still using Rhino 5 and an old Build 0.9.0076, if it should matter

This a lot more sense to me otherwise expression designer get confused with number scientific notation when you use “E” in the middle of curly braces.
