'''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 a compiler extension in [[C++]] and [[C]]. Binary literals typically start with '''0b''' or '''0B''' followed by a series of binary digits. | '''Binary literal''' is an [[integer]] whose value is represented in the source code using the [[binary number system]].

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]]. | 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>.
