Square Roots Computed to At Least 5,000 Decimal Places

Enter a number with no more than 5,000 digits:  

The square root of a positive number "x" is defined to be that number "a" that has the property that "a" multiplied by "a" is equal to "x".
Results computed to 60,000 decimal places are available here for all positive integers between 1 and 100,000. These results were computed at the rate of approximately one or two per minute on a Dell XPS 410 computer in the year 2008. The values were computed to an extra 200 decimal places using a Taylor series approach and then truncated, not rounded, to yield the published significance.

For all other numbers, results are calculated in real time to the first 5,000 digits.

For values of the square roots of some small numbers, calculated to at least one million digits, see: http://antwrp.gsfc.nasa.gov/htmltest/rjn_dig.html.
