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.
