2 digits - return number of "decimal" digits in an integral part
9 b integer >= 2, defaults to 10
14 Returns number of digits in the standard base-b representation
15 when x is truncated to an integer and the sign is ignored.
17 To be more precise: when abs(int(x)) > 0, this function returns
18 the value 1 + ilog(x, b). When abs(int(x)) == 0, then this
19 function returns the value 1.
21 If omitted, b is assumed to be 10. If given, b must be an
24 One should remember these special cases:
26 digits(12.3456) == 2 computes with the integer part only
27 digits(-1234) == 4 computes with the absolute value only
28 digits(0) == 1 specical case
29 digits(-0.123) == 1 combination of all of the above

35 > print digits(0), digits(1), digits(-1)
38 > print digits(-1234), digits(12.3456), digits(107.207)
41 > print digits(17^463-1, 17), digits(10000, 100), digits(21701, 2)
