Interact sliders should be able to have negative step size
|Reported by:||kcrisman||Owned by:||itolkov, jason|
Stepping backwards on sliders. Currently,
@interact def _(n=slider(100,0,-1,1)): print n
gives the error
ValueError, "invalid negative step size -- step size must be positive"
as far as I know. Allowing this could be very helpful, but maybe there was a reason not to do this I am unaware of - the explicit ValueError? leads me to think so, since whoever wrote it put knew this could happen!
