110100100

110100100 is a binary numeral consisting of nine digits, all of which are either 0 or 1. In binary notation it denotes an integer and can be used as a bit pattern in computing. When interpreted as a binary value, 110100100 equals decimal 420. In other common numeral systems, this value is represented as 0x1A4 in hexadecimal and 644 in octal. The decimal-to-binary conversion can be verified by summing powers of two: 2^8 + 2^7 + 2^5 + 2^2 = 256 + 128 + 32 + 4 = 420.

As a nine-bit sequence, it is wider than a byte and is sometimes encountered in contexts where 9-bit data or flags are relevant, such as certain digital signal processing schemes or historical computer architectures. In programming languages that support binary literals, it may be written directly as a binary constant, for example 0b110100100, to represent the same value.

If treated as a bit pattern rather than merely a number, the individual bits can be interpreted as flags or fields according to a given encoding. The meaning of each bit depends on the specific data structure or protocol in which the pattern is used; without such context, 110100100 primarily serves as an example of binary representation and its corresponding decimal, octal, and hexadecimal values.
