0b11110101

0b11110101 is an eight-bit binary literal commonly used in programming and digital electronics to denote the bit pattern 11110101. The prefix 0b signals that the digits that follow are in base 2. The value can be interpreted in multiple ways depending on width and signedness.

When interpreted as an unsigned 8-bit value, 0b11110101 equals decimal 245 and hex 0xF5. In two's complement, which is the standard for signed integers on most modern hardware, the same pattern represents -11.

Bit pattern details: from most significant to least significant bit, the bits are 1 1 1 1 0 1 0 1. This means bits 7, 6, 5, 4, 2, and 0 are set, while bits 3 and 1 are clear. Such a pattern can serve as a bit mask or part of a register value in low-level programming or hardware interfacing.

Character encoding: in ISO/IEC 8859-1 (Latin-1) and Unicode, the byte 0xF5 maps to the character 'õ' (U+00F5). In UTF-8, 0xF5 as a standalone byte is not a valid UTF-8 character and would appear only as part of a multi-byte sequence.

In programming, binary literals like 0b11110101 appear in languages that support binary notation, such as Python, Java, and C++. They are used in low-level code, bitwise operations, and hardware interfacing.
