6.57 Binary constants using the `0b' prefix

Integer constants can be written as binary constants, consisting of a sequence of `0' and `1' digits, prefixed by `0b' or `0B'. This is particularly useful in environments that operate a lot on the bit-level (like microcontrollers).

The following statements are identical:

 i = 42;
 i = 0x2a;
 i = 052;
 i = 0b101010;

The type of these constants follows the same rules as for octal or hexadecimal integer constants, so suffixes like `L' or `UL' can be applied.
