Dear Sir/Mdm,
I would like to ask some information about Haskell. For the information, I'm a
student that currently studying at Bina Nusantara University, Jakarta, Indonesia and
taking computer science as my subject. In Indonesia, we've never learned about
Haskell. It's not populer in Indone

So much for my small, innocuous, non controversial suggestion :-).

The above doesn't work since div can only be applied to integral numbers:

Title: Dividing floats
Can anyone please help me.
How can you divide two floats? (and return a float, even if they divide equally)
Ie (something like...) div 2.4 1.2 ---> 2.0

Haskellers welcome!

Applications are invited for two posts of teaching assistant in the Computing
Laboratory at the University of Kent. These posts are for a fixed-term period
of four years and are intended to support
I don't think there was a deep reason, but

Indeed.
