I'd like to propose what I believe is a simple but valuable extension to Haskell that I haven't seen proposed elsewhere.
C has something it calls hexadecimal floating constants, and it would be very nice if Haskell had it too. For floating point systems where the radix is a power of two (very common), they offer a means of clearly and exactly specifying any finite floating point value.

Similarly, the greatest finite double value can be written as 0x1.fffffffffffffp+1023.
These constants have the form
0x[HH][.HHHHH]p[+/-]DDD
If you don't want to wait on an (uncertain) inclusion into the Haskell standard, you can implement a small helper function to that effect yourself; essentially using encodeFloat . Regards, Heinrich Apfelmus -- http://apfelmus.nfshost.com
