Andrey and group-

would you consider adding in the convention of degrees - minutes - seconds for angle units?
Surveyors and machinists use the convention to define angles.

I can enter angles by defining custom units as smin: deg/60 and ssec = deg/3600. but getting the results out is tricky since there is some logic involved to handle the decimal degree.

(The last year has found me changing careers from professional engineering to teaching at a tech college. I am implementing smath into a couple of my classes and so far their response is great. thanks to all who have donated their training an teaching resources.)
