6.9.2. Binary integer literals¶
-
BinaryLiterals¶ Since: 7.10.1 Status: Included in GHC2024,GHC2021Allow the use of binary notation in integer literals.
Haskell 2010 and Haskell 98 allows for integer literals to be given in
decimal, octal (prefixed by 0o or 0O), or hexadecimal notation
(prefixed by 0x or 0X).
The language extension BinaryLiterals adds support for expressing
integer literals in binary notation with the prefix 0b or 0B. For
instance, the binary integer literal 0b11001001 will be desugared into
fromInteger 201 when BinaryLiterals is enabled.
