0b111000101

0b111000101 is a binary numeral literal used in programming to denote a number in base two. The prefix 0b signals binary notation in many languages, including Python, JavaScript (ES6 and later), and others.

The digits form a 9-bit pattern, and its value is 453 in decimal. This is because the bits correspond to 2^8, 2^7, 2^6, 2^2, and 2^0: 256 + 128 + 64 + 4 + 1 = 453. As an unsigned 9-bit value, the range is 0 to 511. If interpreted as a signed 9-bit two's complement value, the same bit pattern would represent -59.

In hex, 0b111000101 equals 0x1C5. The set bits are at positions 0, 2, 6, 7, and 8 (counting from the least significant bit). Such a pattern can be used as a bitmask or flag field in low-level programming, where each bit represents a power of two or a particular feature.

The use of binary literals helps make bitwise operations and hardware-oriented configurations clear. Prefix 0b is not standardized in all languages, but it is widely supported in many modern ones.
