Gcode conversion with expression

Hi Forum,

Im currently trying to convert quite simple lines into gcode and im having trouble with one Parameter.
see for your self!
Gcode expression.gh (9.5 KB)

as the picture doesnt work:

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.
