0xE7

0xE7 is a hexadecimal literal commonly used in programming to denote the value 231 in decimal. The 0x prefix signals base-16, followed by the digits E and 7. In decimal, 0xE7 equals 231. In binary, it is 11100111.

As an 8-bit unsigned value, 0xE7 is 231. As an 8-bit signed two's-complement value, it equals -25.

In character encodings, 0xE7 corresponds to the character ç in ISO/IEC 8859-1 (Latin-1) and Unicode code point U+00E7. In UTF-8, the same code point U+00E7 is encoded as two bytes: C3 A7; thus a standalone 0xE7 does not appear in valid UTF-8 on its own.

Common uses include representing a byte value in data, bitwise operations, memory addresses, and color channels in some contexts when combined with other bytes (e.g., as part of a 0xRRGGBB value). In many programming languages, 0xE7 is a valid integer literal; its interpretation depends on type and context.

Numerically, 231 factors as 3 × 7 × 11; it is odd and not prime. It is congruent to 7 modulo 16, a reflection of its hexadecimal form.
