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 repeating decimal commonly written as 0.999... represents exactly the same quantity as the number one. Despite having the appearance of representing a smaller number, 0.999... is a symbol for the number 1 in exactly the same way that 0.333... is an equivalent notation for the number represented by the fraction 1 ⁄ 3.

Following the rise in the price of silver during the California Gold Rush and the disappearance of circulating silver coins, the Coinage Act of 1853 reduced the standard for silver coins less than $1 from 412.5 grains to 384 grains (24.9 g), 90% silver per 100 cents (slightly revised to 25.0 g, 90% silver in 1873).
But every number, including π, can be represented by an infinite series of nested fractions, called a simple continued fraction: = + + + + + + + + Truncating the continued fraction at any point yields a rational approximation for π ; the first four of these are 3 , 22 / 7 , 333 / 106 , and 355 / 113 .
In probability theory and statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.The general form of its probability density function is = (). [citation needed]
The United States has a highly developed mixed economy. [40] [41] [42] It is the world's largest economy by nominal GDP and second largest by purchasing power parity (PPP). [43]As of 2024, it has the world's sixth highest nominal GDP per capita and eighth highest GDP per capita by PPP). [10]
In the 1950s, shipping costs made up 33 percent of the price of oil transported from the Persian Gulf to the United States, [101] but due to the development of supertankers in the 1970s, the cost of shipping dropped to only 5 percent of the price of Persian oil in the US. [101]
Price inflation fell dramatically between 2003 and 2004, from 14.2 percent to a 30-year low of 4.3 percent. President's Duarte's economic reforms and austerity programs have produced results more rapidly than many expected.
