I suggest
to incorporate two of the main piecewise functions (defined like in Derive) in a way that it be possible not only graph but operate too (for example for define another piecewise functions)
step(x)=0 if x<0, step(x)=1 if x>=0
floor(x)=0 if x is in [0,1), =1 if x is in [1,2), =2 if x is in [2,3),
