### 5.55 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.
