In this way, numbers up to 10 3·999+3 = 10 3000 (short scale) or 10 6·999 = 10 5994 (long scale) may be named. The choice of roots and the concatenation procedure is that of the standard dictionary numbers if n is 9 or smaller. For larger n (between 10 and 999), prefixes can be constructed based on a system described by Conway and Guy. [17]
[contradictory] For example, the number 4 000 000 has a logarithm (in base 10) of 6.602; its order of magnitude is 6. When truncating, a number of this order of magnitude is between 10 6 and 10 7. In a similar example, with the phrase "seven-figure income", the order of magnitude is the number of figures minus one, so it is very easily ...
1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.
For higher powers of ten, naming diverges. The Indian system uses names for every second power of ten: lakh (10 5), crore (10 7), arab (10 9), kharab (10 11), etc. In the two Western systems, long and short scales, there are names for every third power of ten. The short scale uses million (10 6), billion (10 9), trillion (10 12), etc.
At this scale, the width of a human hair is about 10 times that of the image. [70] To help compare different orders of magnitude this section lists lengths between 10 −8 and 10 −7 m (10 nm and 100 nm). 10 nm Shortest extreme ultraviolet wavelength or longest X-ray wavelength [71] 10 nm – the average length of a nanowire
Trillion is a number with two distinct definitions: 1,000,000,000,000, i.e. one million million, or 10 12 (ten to the twelfth power), as defined on the short scale. This is now the meaning in both American and British English. 1,000,000,000,000,000,000, i.e. 10 18 (ten to the eighteenth power), as defined on the long scale. This is one million ...
Over the last 30 years, the nation's debt has skyrocketed from almost $10 trillion in 1994 to over $35 trillion in 2024, according to recent data from the Department of the Treasury. The federal ...
The number of cells in the human body (estimated at 3.72 × 10 13), or 37.2 trillion/37.2 T [3] The number of bits on a computer hard disk (as of 2024, typically about 10 13, 1–2 TB), or 10 trillion/10T; The number of neuronal connections in the human brain (estimated at 10 14), or 100 trillion/100 T
