Float Arithmetic: Return A Fixnum When Float == Fixnum

[MaggotChild]

j = 5/2.0
=> 2.5

I'm fine with this
=> 2.0

Useless precision -for me. I want 2!
=> 2

Is there a "better" way?

The notation is misleading. It's not a question of precision, but of
type. You can think of 2.0 as 2:Float, not 2 to 2 significant figures.

Why even bother?

It occurs to me that you may also want to play with Rational.

Yes, I do, but when it comes to printing, Float does not.

You can always redefine Float.to_s. Changing the underlying type,
though, is probably a poor idea.

Apply your OCD in the right places, though!

Ugly, but what the hey:

j =3D 2.0
sprintf('%g', j) --> "2"

j =3D 2.50000001
sprintf('%g', j) --> "2.5"

Works on integers, too:

j =3D 2
sprintf('%g', j) --> "2"

Ah, I knew it -a better way. And to think, it was with a printf
format... All those years of C down the toilet
