Added nan?, infinite?, degrees->radians, radians->degrees, exact-round, exact-floor, exact-ceiling, exact-truncate to racket/math
Altered TR's random arithmetic testing to generate single-flonums and very small flonums; fails now because of erroneous types Fixes to sgn, sinh, cosh, and tanh: * preserve single-flonum-ness * correct zero sign (-0.0) for negative return values that are smaller than epsilon * correct behavior with NaN and infinite inputs original commit: a713ca8a8b6c7aed987e80d0621484e68bc3c6f5
