Methods of Computing Square Roots - Other Methods

Other Methods

Finding is the same as solving the equation . Therefore, any general numerical root-finding algorithm can be used. Newton's method, for example, reduces in this case to the Babylonian method. Other methods are less efficient than the ones presented above.

A completely different method for computing the square root is based on the CORDIC algorithm, which uses only very simple operations (addition, subtraction, bitshift and table lookup, but no multiplication).

Famous quotes containing the word methods:

    If men got pregnant, there would be safe, reliable methods of birth control. They’d be inexpensive, too.
    Anna Quindlen (b. 1952)

    Commerce is unexpectedly confident and serene, alert, adventurous, and unwearied. It is very natural in its methods withal, far more so than many fantastic enterprises and sentimental experiments, and hence its singular success.
    Henry David Thoreau (1817–1862)
