You can easily do a loop for the whole number portion of y. For the decimal portion that's more math and log than programming

Use the babylonian method which converges quite fast xn+1 = 1/2 * (xn + S/xn)

I suggest using fast exponentiation technique (exponentiation by squaring) for the whole number portion. We can utilize the same technique for the decimal portion; however, this time every time we move one digit forward in base 2 representation of the decimal portion, we calculate the square root of the previous step using babylonian method, or any other efficient method.
