Returns the correctly rounded square root of a positive BigDecimal. This method performs the fast Square Root by Coupled Newton Iteration algorithm by Timm Ahrendt, from the book "Pi, unleashed" by Jörg Arndt in a neat loop.
The code is based on Frans Lelieveld's code , used here with permission.

Parameters:

squarD - The number to get the root from.

rootMC - Precision and rounding mode.

Returns:

the root of the argument number

Throws:

java.lang.ArithmeticException - if the argument number is negative

java.lang.IllegalArgumentException - if rootMC has precision 0
