-------------------------+--------------------------------------------------
We should define a new symbolic function for the derivative of `ceil` or
`floor`.
In Maple:
{{{
> diff(floor(x),x);
floor(1, x)
> diff(floor(x),x,x);
floor(1, x)
> diff(ceil(x),x,x);
floor(1, x)
> eval(diff(ceil(x),x,x),x=1.5);
0
> eval(diff(ceil(x),x,x),x=0);
Error, (in floor) floor is not differentiable at integers
}}}
