Arc is inexplicably lacking trig, exp, and log Okay, I haven't used Arc in a while -- existing Scheme codebase -- but Arc is built on PLT, which is compliant with R5RS, which does include basic math functions: http://www-sop.inria.fr/mimosa/fp/Bigloo/doc/r5rs-9.html http://www-sop.inria.fr/mimosa/fp/Bigloo/doc/r5rs-9.html (search for sin, cos, etc). Did Arc forget how to talk to the numerics library? Rebind "cos" "sin" and "exp"? Is this guy just being stupid? 'splain me please.
