    Greetings,
    I am new to lisp routines and I am trying to find out if there is anything out there that will apply a wastage percentage of thickness of materials. What I am looking for is... a prompt to ask for a thickness of material and another to ask for the thickness of the material so it could output the wasted percentage, i.e.,
    "Enter thickness of material".... .30"
    "Enter gauged thickness of material".... .25"
    then the output would look something like this......
    0.25"
    (83%)


    Thanks

    That's a pretty simple routine to write: get the two variables, divide one
    by the other, multiply by 100 and display the result. Why not try your hand
    at writing a routine, then post your efforts for critique?

    BTW, the way I read your post, the 83% would be the material *utilization*
    rather than the waste.

    Hello Viking,

    something like this:

    (strcat (rtos (* (/ 1 (/ (getreal "Thickness: ") (getreal "Gauged thickness: "))) 100.0) 2 0) "%")
