Literal for Infinity
by Yitzchak Gale 03 Oct '05

03 Oct '05

While checking for floating-point overflow and underflow conditions, I tried to create a somewhat reliable cross-platform Infinity with the literal "1e100000". When GHC 6.4.1 reads this literal, it goes into a deep trance and consumes huge amounts of memory. Shouldn't it immediately recognize such a thing as Infinity? Is there a better way to check for Infinity? I have not yet figured out how to check for NaN at all - because it is not equal to itself. Any suggestions? BTW, I notice that Simon PJ proposed literals for Infinity and Nan several years ago: http://www.haskell.org/pipermail/haskell/2001-August/007753.html Did anything ever come out of this? Regards, Yitzchak

Haddock now in Fedora Extras
by Jens Petersen 03 Oct '05

03 Oct '05

I'm pleased to announce that Haddock has now been included in Fedora Extras for a few days. :) (Since Fedora Core 4, yum is configured for Fedora Extras by default, so users just need to run "yum install haddock" as root to install.) Jens
