Positive part of an array, maximum of two arrays

Feature Request

Hi to the developers,
It would be convenient to have built-in the max or min of an array and a real number, which means taking the max or min in each entry

real[int] aa(nn),res(nn);
real rr;
res=max(aa,rr);

would give res(i)=max(aa(i),rr)

This would simplify and fasten computations, avoiding to make explicit loops.

Then also useful would be the max (resp min) of two arrays of same length

real[int] aa(nn),bb(nn),res(nn);
res=max(aa,bb);

would do res(i)=max(aa(i),bb(i))
Thanks for your consideration.
