Hi Bas, it's because you're using Dutch localization. Commas and points are reversed in Dutch as opposed to the 'neutral' culture. This is my fault, Grasshopper ought to be running in an invariant culture environment, but this hasn't been fixed yet (it will be fixed for the next version).
In the meantime, you can enter expressions such as 1/2 to get values like 0.5. You could also use a slider. If you type in "1/2" in the Number menu, it will work. -- David Rutten Robert McNeel & Associates On Oct 26, 12:22 pm, basbasbas <[EMAIL PROTECTED]> wrote: > I tried to create a square root using the operator 'Power'.
