A binary integer literal is a string of up to 32 binary digits (0s and 1s) followed by the suffix B (or b). Binary literals of the form "0[bB][10]+" are also supported. If fewer than 32 digits are specified, the assembler right justifies the value and fills the unspecified bits with zeros. These are examples of valid binary literals:
| 00000000B | Literal equal to 010 or 016 |
| 0100000b | Literal equal to 3210 or 2016 |
| 01b | Literal equal to 110 or 116 |
| 11111000B | Literal equal to 24810 or 0F816 |
| 0b00101010 | Literal equal to 4210 or 2A16 |
| 0B101010 | Literal equal to 4210 or 2A16 |
