hundredmillion

One hundred million, written as 100,000,000, is the natural number that follows 99,999,999 and precedes 100,000,001. In the decimal system it is represented as a one followed by eight zeros. It is equal to 10^8, making it a central example of a round, easily described large count. The square root of 100,000,000 is 10,000, and it can be expressed as 100^4. In binary and other bases it has a more complex representation, but its decimal form is the most commonly used in everyday arithmetic.

In naming conventions, the number is spoken as “one hundred million.” In English it is typically written as two words rather than a single term, and the single-word form “hundredmillion” is uncommon except in programming identifiers, domain names, or branding. In scientific and formal contexts, it is also written as 1 × 10^8. The prime factorization of 100,000,000 is 2^8 × 5^8, reflecting its composition from powers of ten.

Applications and examples: 100 million serves as a common benchmark in demography, economics, and data analysis. Some national populations exceed this figure, while many datasets and financial figures are reported in the hundreds of millions. In media and communication, it is often used to convey scale without listing many additional digits, such as counts of viewers, subscribers, or units sold.

Note on scale: in the short scale used in English-speaking countries, 100 million equals 0.1 billion. In some long-scale systems, naming differs for larger numbers, but 100 million remains a standard large-count example across languages.
