To clarify things, 1. is not a valid number in Perl 6. 1.0 is a Rat, 1e0 or 1.0e0 are Num.

I've also tried to explicitly declare the loop variable as a floating point:

There are two issues with it. The first is that you don't declare the loop variable to be a Num, but an outer variable of the same name. In -> $i { ... } the part between the arrow and the block is a signature, which declares a new variable. So it's like writing 

my Num $i;
sub ($i) { # new $i here

}

A way to fix that is writing -> Num $i { }, but then you get a type check failure because 1..1000 indeed produces Ints, not Nums. So either you coerce to Num somewhere (for example $i.Num ** 2), or you write the range as 1e0 .. 1e3.

I admit that I posed the original question in a slightly more trollish way than necessary, and I apologize for the inconvenience I might have created. I didn't intend to denigrate the effort of the Perl 6 developers - an effort which is nothing short of heroic.

My side remark was more about _foo's trolling, not about your original question, which I think is 100% valid, and a good bug report at that. Sorry if that came out wrong on my part. User feedback like yours is what we need, and one of the reasons for making the star releases in the first place.
