11111010

11111010 is an eight-bit binary number that is commonly encountered as a single byte in digital systems. It is written as 0b11111010 and corresponds to the hexadecimal value 0xFA.

As an unsigned value, 11111010 equals 250 in decimal. This interpretation is used when the byte represents a non-signed quantity, such as raw data or a color channel value in some contexts.

In signed representations, the meaning depends on the encoding used. In two's complement, which is the standard for most modern computers, 11111010 represents -6. This is obtained by inverting the bits to 00000101 and adding 1 to obtain 00000110, whose magnitude is 6 with a negative sign.

In one's complement representation, 11111010 represents -5, since it is the bitwise complement of 00000101, which is 5.

In sign-magnitude representation, 11111010 denotes -122. The most significant bit indicates the sign (1 for negative), and the remaining seven bits form the magnitude 1111010, which is 122 in decimal.

Overall, the exact value of the pattern 11111010 depends on the signed or unsigned interpretation used. In many modern systems, two's complement is standard for signed integers, while 11111010 is commonly referenced in hex as 0xFA when discussing raw byte values.
