- Field Detail
  - MAX_DECIMAL_DIGITS
```
private static final int MAX_DECIMAL_DIGITS
```
    The resulting value must fit into 2^31 - 1 bits. The decimal representation of 2^31 - 1 bits has 646,456,993 digits.

  - MAX_HEX_DIGITS
```
private static final int MAX_HEX_DIGITS
```
    The resulting value must fit into 2^31 - 1 bits. The hexadecimal representation of 2^31 - 1 bits has 536,870,912 digits.

  - RECURSION_THRESHOLD
```
static final int RECURSION_THRESHOLD
```
    Threshold on the number of digits for selecting the recursive algorithm instead of the iterative algorithm.
    Set this to Integer.MAX_VALUE if you only want to use the iterative algorithm.
    Set this to 0 if you only want to use the recursive algorithm.
    Rationale for choosing a specific threshold value: The iterative algorithm has a smaller constant overhead than the recursive algorithm. We speculate that we break even somewhere at twice the threshold value.
