I see two sequences: -below ;; disables up to -above ;; here; disables up to -below and re-enables tests or -above ;; disables everything up to here and enables tests up to -below ;; here; disables tests below. Anything else? -- Matthias On Nov 28, 2011, at 10:09 PM, Robby Findler

[racket-dev] Subnormal numbers?

2011-11-29 Thread J. Ian Johnson
I'm currently proctoring the freshmen's lab on inexact numbers and was curious how to denote subnormal numbers in Racket. Turns out that's not possible, since there is no underflow. Why does Racket follow the old standard of representing underflow with inexact zero? I imagine changing it now
