It is one way to do it.

Fiddles with floating point calculations (two formats provided). RTFM.

There are several methods for calculating sq root. Search the
archives here and software-eng. THe one the comes to mind is a
sucessive approximation method that (from MSB to LSB) sets a bit in
the answer then squares the number then tests is the guess squared is
larger input value. I suspect the 430 will have fast multiply.
Floating point will be large code and time wise.
