Piecewise functions in CAS
Answered
Dear developers
It would be really nice if something like this would work in CASview:
g(x):=If[4<=x<=5,x1,If[5<x<=7,2x7]]
Solve[g(x)=4]
Also it would be nice if piecewise functions were typeset like in the algebraview.

We won't be able to get that working for Solve, but it (almost) works for NSolve, eg
NSolve[(If[3 < x < 4,x,x+1])=3.5]
NSolve[If[4<=x<=5,x1,If[5<x<=7,2x7,10000000000]]=4]
NSolve[If[4<=x<=5,x1,If[5<x<=7,2x7]]=4]
works in 5.0.30.0
Wow, thanks!
