double square root

  Abstract: This paper mainly discusses how to calculate the square root of a small integer by using the sum of the number of series. This algorithm can accurately return the square root of an integer to any precision when the memory space permits.

X1=1/2 (x0+a/x0)For example, A is 2 o'clock, the square root value: 1.414214#include #include Double Fun (double A, dounle x0){double x1, y;x1= (x0+ a/x0)/2.0;if (Fabs (x1-x0) >=0.00001)Y=fun (A,X1);else y=x1;return y;}Main (){Double x;printf

Title:The root of a number, such as the square root 2, is required to be reserved to 10 digits after the decimal point. Solution One:It is equivalent to seeking a number N of the root, we use the dichotomy method to calculate, shrinking the range,

1. Description of the problem The problem is this, given a number a, to solve the square root of the number, requiring precision f Long time no fencing implementation algorithm code, today to write a small, follow-up algorithm is still

Mathematical principle derivation: f (x) = x2-n---formula (1) n is a value that requires a square root, such as the square root n = 100, which requires 100, so the problem is converted to the 0 point of F (x), the derivative of f (Xn) is the slope

 ----- Edit by ZhuSenlin HDU Given a positive number a, the square root of the database function is not required. Set the square root of x, there is x2 = a, that is, the x2-a = 0. If function f (x) = x2-a, the red function curve is displayed. Take a
