1048576

1048576, also written as 1,048,576, is a positive integer in decimal notation. It equals 2^20, making it a power of two. It is also 1024 squared and 4^10. In hexadecimal, it is 0x100000, and in binary it is a 1 followed by twenty zeros.

In mathematical terms, 2^20 is a perfect square because the exponent is even, so 1,048,576 equals 1024 × 1024. It is also a round figure in binary-based contexts, reflecting common use of powers of two in computing.

In computing and digital storage, 1 mebibyte (MiB) is defined as 1,048,576 bytes. This uses the binary prefix mebibyte to distinguish it from the decimal megabyte (1,000,000 bytes). Because 2^20 underpins binary addressing, 1,048,576 bytes is a familiar block size for memory and storage calculations. The value is also notable in binary arithmetic and computer architecture as a convenient, large power-of-two boundary. It is worth noting that the maximum value of an unsigned 20-bit integer is 1,048,575; 1,048,576 requires 21 bits to represent.

Overall, 1,048,576 is notable mainly for its mathematical properties as 2^20 and its practical role in computing as the number of bytes in one mebibyte, highlighting the distinction between binary-based units and decimal prefixes in data storage.
