Billion. Billion is a word for a large number, and it has two distinct definitions: 1,000,000,000, i.e. one thousand million, or 10 9 (ten to the ninth power ), as defined on the short scale. This is now the most common sense of the word in all varieties of English; it has long been established in American English and has since become common in ...
This section illustrates several systems for naming large numbers, and shows how they can be extended past vigintillion . Traditional British usage assigned new names for each power of one million (the long scale ): 1,000,000 = 1 million; 1,000,0002 = 1 billion; 1,000,0003 = 1 trillion; and so on. It was adapted from French usage, and is ...
1,000,000,000 (one billion, short scale; one thousand million or one milliard, one yard, [1] long scale) is the natural number following 999,999,999 and preceding 1,000,000,001. With a number, "billion" can be abbreviated as b, bil[citation needed] or bn. [2] [3] In standard form, it is written as 1 × 109.
The number of cells in the human body (estimated at 3.72 × 10 13), or 37.2 trillion; The number of bits on a computer hard disk (as of 2024, typically about 10 13, 1–2 TB), or 10 trillion; The number of neuronal connections in the human brain (estimated at 10 14), or 100 trillion
For whole numbers smaller than 1,000,000,000 (10 9 ), such as one thousand or one million, the two scales are identical. For larger numbers, starting with 10 9, the two systems differ. For identical names, the long scale proceeds by powers of one million, whereas the short scale proceeds by powers of one thousand.
Power of 10. Visualisation of powers of 10 from one to 1 billion. A power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power) of ten. The first few non-negative powers of ten are:
Mathematics: 608,981,813,029 is the smallest number for which there are more primes of the form 3k + 1 than of the form 3k + 2 up to the number. 10 12 10 12 stars in the Andromeda Galaxy (1 000 000 000 000; 1000 4; short scale: one trillion; long scale: one billion) ISO: tera-(T)
Euler ascertained that 2 31 − 1 = 2147483647 is a prime number; and this is the greatest at present known to be such, and, consequently, the last of the above perfect numbers [i.e., 2 30 (2 31 − 1)], which depends upon this, is the greatest perfect number known at present, and probably the greatest that ever will be discovered; for as they ...
