* Number#toPaddedString(length[, radix]) -> String
* - length (Number): The minimum length for the resulting string.
* - radix (Number): An optional radix for the string representation,
* defaults to 10 (decimal).
*
* Converts the number into a string padded with 0s so that the string's length
* is at least equal to `length`.
* Takes an optional `radix` argument which specifies the base to use for conversion.
* Returns a string representation of the number padded with leading 0s so
* that the string's length is at least equal to `length`. Takes an optional
* `radix` argument which specifies the base to use for conversion.
*
* ### Examples
*
* (13).toPaddedString(4);
* // -> "0013"
*
* (13).toPaddedString(2);
* // -> "13"
*
* (13).toPaddedString(1);
* // -> "13"
*
* (13).toPaddedString(4, 16)
* // -> "000d"
*
* (13).toPaddedString(4, 2);
* // -> "1101"
