What an interesting coincidence, I was doing some trig just last night,and the conversion from degrees to radians was a minor bother, but abother just the same. Could we have the choice? It would seem to be avery simple thing to add: "setopt ZCALC_DEGREES" "setopt ZCALC_RADIANS"?? ... and of course the internal math would be trivial, but faster andmore accurate than belaboring it in one's code. 20 minutes work (hesaid, with his laughable naivety ;-)
