Lets say that there are a few fractions:
x = 0.584592145015
y = 0.443242244323
How do one convert these fractions to whole numbers? That is:
xw = 584592145015
yw = 443242244323
The point is that the fraction can be upto any amount of precision. Is there a generalized way to determine what power of 10 to multiply with the fraction to convert it to a whole number?
Thanks.

You can think about it this way: Each power of $10$ "moves" the decimal point one place to the right. For example:
$$0.00002times10^5=2$$
For the two numbers in your problem, you can multiply them by $10^12$ to get whole numbers, since there are $12$ digits past the decimal point in each number.

So we can generalize that multiplying with 10^n (where n = number of digits after 0) will give the whole number?

Right. You should try a few examples on your calculator to see that it works.

It’s even simpler than that. Given a number $x$, and an integer $d$, you can form the approximation of $x$ as a fraction $$xapproxfraclfloor dx rfloord$$ where $lfloorcdotrfloor$ just rounds down to an integer.
