01011010

01011010 is an eight-bit binary sequence commonly used in computing as a representation of a numeric value. When read as an unsigned binary number, it equals 90 in decimal; in hexadecimal, it corresponds to 0x5A. In two's complement signed interpretation, the value is also +90.

In character encodings, the byte 01011010 represents the capital letter Z in ASCII. This same bit pattern maps to the Unicode code point U+005A, which is the standard way to encode uppercase Z in many text-processing systems that base their encoding on ASCII.

As a bit pattern, 01011010 can function as a mask or flag in low-level operations. The bits set within the pattern are 64, 16, 8, and 2, which together sum to 90. This demonstrates how binary patterns encode both numeric values and individual bit-level meanings.

In programming languages, 01011010 may appear as a binary literal (for example, 0b01011010 in languages that support such syntax) or as part of binary data in files and network protocols. It is a common example used to illustrate binary-to-decimal and ASCII mappings.
