Decimal Representation of Real Numbers
... If you give the first few decimal places of a real number, you are giving an approximation to it. Mathematicians on the one hand and scientists and engineers on the other tend to treat expressions such as " 3.14159" in two different ways. The mathematician may think of it as a precisely given numb ...

... Mixed numbers consist of a whole number and a fraction. Basically, any decimal that is greater than one can be represented as a mixed number. Look at a decimal like 2.5 and think of it as 2 + 1/2. So, as a mixed number, 2.5 can simply be written as 2 ½. Mixed numbers can also be written as improper ...

Approximations of π
Approximations for the mathematical constant pi (π) in the history of mathematics reached an accuracy within 0.04% of the true value before the beginning of the Common Era (Archimedes). In Chinese mathematics, this was improved to approximations correct to what corresponds to about seven decimal digits by the 5th century.Further progress was made only from the 15th century (Jamshīd al-Kāshī), and early modern mathematicians reached an accuracy of 35 digits by the 18th century (Ludolph van Ceulen), and 126 digits by the 19th century (Jurij Vega), surpassing the accuracy required for any conceivable application outside of pure mathematics.The record of manual approximation of π is held by William Shanks, who calculated 527 digits correctly in the years preceding 1873. Since the mid 20th century, approximation of π has been the task of electronic digital computers; the current record (as of May 2015) is at 13.3 trillion digits, calculated in October 2014.
