Hi Norman,
Much better!
Question: Rat:
https://docs.raku.org/type/Rat
Rat objects store rational numbers as a pair
of a numerator and denominator. Number literals
with a dot but without exponent produce Rats.
What does Rat do to sqrt(2) to give it a numerator
and a denominator?
And I see base-repeating wants to be fed a Rational:
https://docs.raku.org/routine/base-repeating
Also I much prefer:
$ perl6 -e 'say <1/7>.base-repeating();'
(0. 142857)
over
$ perl6 -e 'say (1/7).base-repeating();'
(0. 142857)
As to me (1/7) means solve the equation and then
send it on.
Also, what is base-repeating telling me? Where the
repeat is? What the repeat is?
And what if I only want to see if a repeat occurs
in a single number, not a Rat/Rational?
$ perl6 -e 'say <0.9876123412341234/1>.base-repeating();'
(0.9876123412341234 )
I am doing something wrong.
Many thanks,
-T
