max 6.1.2: bug in flonum display
Max Patch
Copy patch and select New From Clipboard in Max.
the display of the floating point number box can't recover correctly from 'nan' values.
(max 6.1.2 - osx 10.6.8)
I can repro. As you said it's a display issue. You can send the flonum's output to a message box and the result is correct so the output is at least working.
I believe this will be fixed up for the next update.
Thanks,
