1000010001

1000010001 is a binary numeral used in digital systems to represent an integer. It consists of ten bits, with 1s in the most-significant bit (bit 9), the fifth bit (bit 4), and the least-significant bit (bit 0).

As a base-2 number, its decimal value is 529, calculated as 2^9 + 2^4 + 2^0. In hexadecimal, it equals 0x211, a form often used in programming and debugging to simplify bit-level inspection and representation.

The pattern is not a palindrome, and its bit pattern—ones at positions 9, 4, and 0—provides a simple example of a sparse bit set. Such ten-bit values can appear as bitmasks or flags in embedded systems, digital encodings, or data tests. While 1000010001 by itself is not a standard constant with wide historical significance, it serves as a clear illustration of binary arithmetic and bitwise representation, and it can be used to demonstrate how individual bit positions contribute to a total value in teaching or low-level software development.
