11101001

11101001 is an eight-bit binary value. When interpreted as an unsigned integer, it equals 233 in decimal and 0xE9 in hexadecimal.

In the common 8-bit, two's complement system used for signed integers, 11101001 represents −23. This follows from the rule that values with the most significant bit set to 1 are negative in that representation.

In character encoding terms, the byte 0xE9 corresponds to the character é in ISO/IEC 8859-1 (Latin-1) and the Windows-1252 encoding. In Unicode UTF-8, however, 0xE9 is not a standalone character; it would serve as the lead byte in a three-byte sequence, with the actual code point encoded across multiple bytes.

Bitwise properties of 11101001 include its status as an odd number and its most significant bit being 1. The bitwise NOT of 11101001 is 00010110 (0x16). Such patterns are commonly used in computing to illustrate basic byte operations, bit masking, and encoding schemes.

Applications and significance: 11101001 often appears in examples involving binary arithmetic, memory dumps, or data encoding discussions. Its various interpretations—unsigned value, two's complement signed value, and encoded character in certain legacy encodings—illustrate how the same bit pattern can carry different meanings depending on context.
