1000100001

1000100001 is a ten-bit binary numeral. When interpreted as an unsigned integer, it equals 545 in decimal. In hexadecimal, it corresponds to 0x221.

The number has ones in bit positions 9, 5, and 0 (counting from the least significant bit as position 0). This yields 2^9 + 2^5 + 2^0 = 512 + 32 + 1 = 545. The remaining bits are zero. The sequence is not a palindrome; its reverse is 1000010001.

In an arithmetic context using 10-bit two's complement representation, the most significant bit indicates sign, so 1000100001 represents -479.

It is a simple, non-special binary pattern that may appear in examples and test data for digital circuits, encoding demonstrations, or numeral-conversion exercises. It does not correspond to a standard ASCII or Unicode code point, and it does not indicate any widely used constant beyond its numeric value.
