0b111000

0b111000 is a binary literal commonly used in programming to denote the base-2 representation of a value. The digits 111000 correspond to the decimal value 56 and the hexadecimal value 0x38. It is a six-bit pattern, with the upper three bits set (32, 16, and 8) and the lower three bits cleared.

In common-width storage, such as an 8-bit byte, 0b111000 is often represented as 00111000, with leading zeros added to fit the width. The exact width can vary, and the value remains the same when interpreted as an unsigned integer.

Binary literals like 0b111000 are used in programming for bitwise operations, masks, flags, and low-level hardware control, where the precise bit pattern matters. They enable direct specification of bit patterns without needing to convert from other bases.

The 0b prefix is a conventional indicator of a binary literal in languages such as Python and JavaScript; not all languages support binary literals natively, and some require alternative notations such as hexadecimal or decimal with explicit masks. When documenting or sharing code, it is helpful to note the intended width and any surrounding context that might affect interpretation.
