Units and Precision?

by Chris

Ive got a little problem

We're building a scale model of a site plan, the units are in [m] in rhino because when i change it to [mm], grasshopper is not recognizing the base surface (which is relevant for projections)

Im running a boolean operation and want each house in this random looking town to move up or down by .0001m just so i can run this operation.

The random generator is fine but it seems to spit out up to .001, as in its rounding up

how can i set the precision to be much higher in grasshopper, is there a function for this or does it come out of rhino? 

I have tried everything


thanks guys

    Hi Chris,

    the random number generator returns pseudo-random numbers which have (generally) many decimal digits.
    The panel and the preview, though, do not show by default all figures after the point, but these digits should still be taken into account if you use the result directly inside any component that expects floating point numbers (doubles).

    Here an example:


    I hope it helps,
