How to get the ASCII value of a character in Haskell? I've tried to use the ord function in GHCi, based on what I read here bug the the error message:
Not in scope: `ord'
For example:
GHCi, version 6.12.1: http://www.haskell.org/ghc/ :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
Prelude> ord 'a'
<interactive>:1:0: Not in scope: `ord'
Prelude>
What am I doing wrong?
