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