A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor. For example, the value 1.23 can be stored in a variable as the integer value 1230 with implicit scaling factor of 1/1000 (meaning that the last 3 decimal digits are implicitly assumed to be a decimal fraction), and the value 1 230 000 can be represented ...
The oldest known multiplication tables were used by the Babylonians about 4000 years ago. [2] However, they used a base of 60. [2] The oldest known tables using a base of 10 are the Chinese decimal multiplication table on bamboo strips dating to about 305 BC, during China's Warring States period. [2] "Table of Pythagoras" on Napier's bones [3]
Critical values of the studentized range distribution are used in Tukey's range test. [3]The studentized range is used to calculate significance levels for results obtained by data mining, where one selectively seeks extreme differences in sample data, rather than only sampling randomly.
[100] [101] [102] The aftermath of the Air West deal was later settled with the SEC by paying former stockholders for alleged losses from the sale of their investment in Air West stock. [103] As noted above, Air West was subsequently renamed Hughes Airwest. During a long pause between the years of the dismissed charges against Hughes, Charnay ...
Mathematically, density is defined as mass divided by volume: [1] =, where ρ is the density, m is the mass, and V is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume , [ 2 ] although this is scientifically inaccurate – this quantity is more ...
Considering only those who marked "black" and no other race in combination, as in the first table, the percentage was 12.4% in 2020, down from 12.6% in 2010. [1] Considering those who marked "black" and any other race in combination, as in the second table, the percentage increased from 13.6% to 14.2%.
Based on the 2010 United States federal budget, total national debt will grow to nearly 100% of GDP, versus a level of approximately 80% in early 2009. [377] The White House estimates that the government's tab for servicing the debt will exceed $700 billion a year in 2019, [ 378 ] up from $202 billion in 2009.
India occupies 2.41% of the world's land area but supports over 18% of the world's population. At the 2001 census 72.2% of the population [100] lived in about 638,000 villages [101] and the remaining 27.8% [100] lived in more than 5,100 towns and over 380 urban agglomerations. [102]
