Character and numeric types

There are the following obvious primitive types: 
type Char#
type Int#       -- see also Word# and Addr#, later
type Float#
type Double#
If you really want to know their exact equivalents in C, see `ghc/includes/StgTypes.lh' in the GHC source tree. Literals for these types may be written as follows: 
1#              an Int#
1.2#            a Float#
1.34##          a Double#
'a'#            a Char#; for weird characters, use '\o<octal>'#
"a"#            an Addr# (a `char *')
