Square root

[eWhabs]

At school we were talking about Square and algebra, and this question came into my mind: "How do computers calculate the square root of a number?".

Do they have some kind of list and makecalculations to determine what the number is?

What do you think?

When computers return square roots, they return an approximation. I don't know the algorithm used to return this approximation though.

A question like this was asked a week or so ago. The square root of a number x can be calculated as such: e^(0.5*ln(x));
