299999999

299,999,999 is an integer in the decimal system. It equals 300,000,000 minus 1 and is written as 299,999,999. The number is nine digits long, featuring a leading 2 followed by eight 9s, which gives it a distinctive decimal pattern.

In basic number theory, 299,999,999 is not divisible by 2, 3, or 5, since it ends in 9 and the sum of its digits is not a multiple of 3. It is not a perfect square, as it lies between 547^2 = 299,209 and 548^2 = 300,304. In binary, it lies between 2^28 and 2^29, meaning it requires 29 bits for its standard binary representation.

From a computational perspective, 299,999,999 is well within the range of common integer types in most programming languages. For 32-bit signed integers, its value is safely representable, and it is also easily stored in unsigned 32-bit formats. Its decimal form with many trailing 9s makes it a frequent example in discussions of formatting, numeric patterns, and boundary cases in software demonstrations.

There is no widely recognized cultural or mathematical significance attached to this specific number beyond its role as a large, near-round decimal value. It is often encountered as a convenient example or test figure in mathematical and computer science contexts, particularly because it is 1 less than a large, round threshold (300,000,000).
