MapRange - source range 0

with 0 at the source width pin MapRange outputs MaxFloat.

on the other hand having the same inputs on source min and source max @ Map works fine

hmm. sounds like the more mathematically plausible output; especially as it nicely toggles between -INF and +INF, or DestMin and DestMax depending on the Mapping mode.

Map outputs the more userfriedly Destmin iirc.

what is the more desirable behaviour?
