bigSqrt

public static BigDecimal bigSqrt(BigDecimal squarD,
 MathContext rootMC)

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:

ArithmeticException - if the argument number is negative

IllegalArgumentException - if rootMC has precision 0
