So, we can say thatthe square root of 2.1609 is 1.47with an error smaller than 0.01 (in fact the error is 0.0016000481). this means that the first 2 decimal places are correct. Just to compare, the returned value by using the javascript function 'Math.sqrt(2.1609)' is 1.47. ...
The square number of an even integer is always an even integer, while the square of an odd number is always an odd number. Square numbers are always positive. If a number’s square root is a fraction or a decimal number, it is not a perfect square number. For instance, 0.25=0.5,...
Suppose we have an estimate, xest, for the square root of a number y, whose accuracy we measure with the following error function: err(x,y) = y - xest2 Then we might be interested in the error of a better estimate x+p, err(xest+p,y): ...
