A binary self-defining term is written as an unsigned sequence of 1s and 0s enclosed in apostrophes and preceded by the letter B; for example, B'10001101'. A binary term can have up to 32 bits, not counting leading zero bits. This allows a range of values from -2,147,483,648 through 2,147,483,647.

When used as an absolute term in an expression, a binary self-defining term has a negative value if the term is 32 bits long and the high-order bit is 1.

Binary representation is used primarily in designating bit patterns of masks or in logical operations.
