Method Details

toString

public static String toString(long value,
int radix)
                       throws IllegalArgumentException

Constructs and returns a representation of value using radix as a number base. The characters used for the digits of the representation are '0' through '9', supplemented (as necessary) by 'a' through 'z' (for radix > 10). This gives a maximum of 36 digit characters; thus, an IllegalArgumentException is thrown if radix > 36, or if radix <= 1. If value < 0, then the representation returned is the same as the representation that would be returned for Math.abs(value), but with "-" prepended.

Parameters:

value - Quantity to be represented using radix as a number base.

radix - Number base to use in the representation of value.

Returns:

Representation of value using radix as a number base.

Throws:

IllegalArgumentException - If radix <= 1, or if radix > 36.
