I propose to modify the built-in function int(4) such that it can handle integration variables with units. It is easy to build a corresponding function thanks to Davide's UoM() and for maple(int(4) this already works.

[MATH lang=eng]Int(f#,x#,a#,b#):line(u#:UoM(b#-a#),sf#:num2str(f#),sx#:num2str(x#),sxu#:num2str(x#*u#),ft#:str2num(strrep(sf#,sx#,sxu#)),u#*int(ft#,x#,a#/u#,b#/u#),6,1)[/MATH]

See attached sheet for examples.

Edit: Shifted to bug tracking system
