0b00100101

0b00100101 is a binary literal used in programming languages that recognize the 0b prefix to denote binary numbers. The sequence comprises eight bits.

Value: As an unsigned binary number, 0b00100101 equals decimal 37 and hexadecimal 0x25. The ones occur at bit positions 0, 2, and 5 (counting from the least significant bit), giving a bitmask of 1 + 4 + 32 = 37.

Context and usage: Such a literal defines a specific bit pattern for initialization or for bitwise operations (AND, OR, XOR, NOT). It can represent a set of flags or a mask in low-level programming tasks. In ASCII, the byte 0x25 corresponds to the character '%'. In an 8-bit byte context, the most significant bit is 0, so the value is non-negative in two's complement representation.
