Editing binary literal

'''Binary literal''' is an [[integer]] whose value is represented in the source code using the [[binary number system]]. Binary literals are a feature supported in many programming languages such as [[Java]], [[D]] and [[Python]] as well as in a compiler extension in [[C++]] and [[C]]. Binary literals typically start with '''0b''' or '''0B''' followed by a series of binary digits.

== Programming languages ==
=== Java ===
Starting with [[Java 7]], binary literals are possible to be expressed using the 0b or 0B prefix. For example:

<source lang="Java">
//an octet value
byte b = (byte)0b00010101;

//a 32-bit integer value
int i = 0b001101010110101010001111011101;
int i2 = 0b1110;
</source>

=== Python ===
Starting with Python 2.6, binary literals support was added via the "0b" and "0B" prefixes.<ref>[http://docs.python.org/release/3.2.3/reference/lexical_analysis.html#integerliterals 2. Lexical analysis]</ref>

=== Lisp ===
Lisp supports binary literals to represent integers and rational values via the '''#b''' prefix, for example:

<source lang="lisp">
#b10111

; rational values
#b1110/1111 
</source>

=== C++ and C ===
Binary literals already exist in the C++ and C languages in the form of non-standard compiler extensions<ref>[http://gcc.gnu.org/onlinedocs/gcc/Binary-constants.html 6.62 Binary constants using the ‘0b’ prefix]</ref>. They are prefixed with 0b or 0B followed by a series of binary digits. Binary literals have also been proposed<ref>[http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3472.pdf C++14 N3472 Binary Literals in the C++ Core Language]</ref> as a core language addition in [[C++14]].
