## (Rational) method base-repeating

method base-repeating(Rational: Int() = 10)

Returns a list of two strings that, when concatenated, represent the number in base `$base`

. The second element is the one that repeats. For example:

my (, ) = (19/3).base-repeating(10);say ; # OUTPUT: «6.»say ; # OUTPUT: «3»printf '%s(%s)', , ; # OUTPUT: «6.(3)»

19/3 is 6.333333... with the 3 repeating indefinitely.

If no repetition occurs, the second string is empty:

say (5/2).base-repeating(10).raku; # OUTPUT: «("2.5", "")»

The precision for determining the repeating group is limited to 1000 characters, above that, the second string is `???`

.

`$base`

defaults to `10`
