When asking for continued fractions, we should determine how much precision is required. Continued fractions provide a very effective toolset for approximating functions. Every rational number has a simple continued fraction expansion which is nite and every nite simple continued fraction expansion is a rational number. without the dots, in Wolfram Alpha; or use an online continued fraction calculator.) Usually the continued fraction expansion of a function approximates the function better than its Taylor or Fourier series. It also shows the continued fraction coefficients (the first coefficient is the integer part). the section on Pell's equation states: Continued fractions play an essential role in the solution of Pell's equation. Convert a fraction to a decimal or percent or vice versa. The most important and well-known theorems throughout mathematics are often named after their inventors. Behind the Feigenbaum Constant.

The convergents of the continued fraction whose value is n represent the best possible rational approximation to n in the sense that no fraction with a smaller denominator is closer. Fields above the solid black line represent the numerator, while fields below represent the denominator. Some care is needed, since some authors begin indexing the terms at instead of , causing the parity of certain fundamental results in continued fraction theory to be reversed.The first terms of the simple continued fraction of a number can be computed in Mathematica using the command ContinuedFraction[x, n]..
