00011100

00011100 is an eight-bit binary numeral. When read as a binary number, it equals the decimal value 28 and the hexadecimal value 0x1C. The bit pattern is often written with spaces as 0001 1100 for readability.

In ASCII and Unicode, the byte 0x1C corresponds to the File Separator (FS) control character (Unicode U+001C). It is a non-printable control code used in legacy data streams and certain protocol delimiters.

As a bitmask, 00011100 has ones in bit positions 2, 3, and 4 (counting from zero). This makes it a common example when illustrating how individual flags within a byte can be turned on or off. For example, if bits 2–4 represent options A, B, and C, a value of 28 would indicate that those options are enabled.

In mathematics, the decimal value 28 is a perfect number, since the sum of its proper divisors (1, 2, 4, 7, 14) equals 28. This is a property of the number 28, independent of its binary representation.
