I am working on a BigDec number type.

You know BigInt, right?  Using Turbowarp, I'm creating a version that supports decimal numbers.
This isn't a floating point, though.  It's a fixed-point number system, so I don't have to worry about the number of decimal digits...

I just got done with making the square root operator, and it is VERY FAST.  Like, so fast my mind can't comprehend it.

I did the square root of 2^10,001, and after 4 seconds, it gave me THE CORRECT ANSWER!  (I checked using Wolfram Alpha)
