Fixed bigfloat functions that assumed (fixnum? x) means x fits in a _long (not true on Win64) Hopefully fixed dangling pointer errors that broke `math/bigfloat' on Win64. It apparently had no _long/_int mismatches, but GC on Win64 will run between creating an `_mpz' and using its value after passing it as an output argument to MPFR functions. That doesn't seem to happen on 64-bit Linux or Mac. No idea why, but Win64 exposed the problem so... that's good, I guess. Rewrote `rational->bigfloat' to not use GMP's rationals More/better bigfloat tests Added bigfloat stress test w/ weak leak detection Reenabled custodian shutdown callback that clears MPFR constants, because it seems to work now Removed `mpfr-available?' because it would only return non-#f |

The Racket programming language =============================== Important executables: * DrRacket: Racket's integrated development environment (start here!). * Racket: the main command-line entry point for running racket programs and scripts. * GRacket: the GUI-mode Racket executable. * raco: Racket's command-line toolset. More Information ---------------- Racket comes with extensive documentation: use DrRacket's `Help' menu, or run `raco docs'. Also, visit us at http://racket-lang.org/ for more Racket resources.
