Also, going by math calling the "real numbers" misses that math treats integers as a subset of real numbers; there is no hard distinction between them in math. Computers need hard distinctions here because integral, rational, and floating point numbers must be stored in different ways, unless they take the PHP / Javascript solution (storing them all as strings or floating point, respectively). Perl 6's Real is a role that the actual types "does" if they are compatible with it.
If you want to do the Perl 5-ish thing where it hid the differences (and sometimes promoted an integral value to floating without asking, never to return), use the Real role as a type to hide the difference between them. If you want to be specific, use the correct type. On Sun, Sep 16, 2018 at 11:51 PM Brandon Allbery <allber...@gmail.com> wrote: > You're assuming "Real" means "a float of some kind".
