Re: What's something you don't understand, even when it's explained to you?

[cbrachyrhynchos]

It's simple:

1/3 = .333(repeating)
2/3 = .666(repeating)
3/3 = .999(repeating)

All you're looking at is a difference in notation.

I thought 2/3 was supposed to equal 6.666......67

Re: What's something you don't understand, even when it's explained to you?

[(Anonymous)]

Nope, it equals .6666.... repeating. We just end it with a 7 for the sake of rounding, but precisely, it's .66666... to infinity.

That's rounded off to an arbitrary number of digits because most calculators can't handle rational numbers.

You mean can't handle irrational numbers? :P

But yeah, ok, that makes sense.

Re: What's something you don't understand, even when it's explained to you?

[cbrachyrhynchos]

It's a rational number if it can be expressed as a whole-number fraction. These can also be expressed as a repeating decimal (1/3 = 0.333(repeating)) or a terminating decimal (1/4 = 0.25). Some programming languages (primarily the lisp family) have a rational type that's used to avoid rounding errors although the fractions often become unreadable.

Irrational numbers don't have a repeating pattern in decimal notation.

Re: What's something you don't understand, even when it's explained to you?

[diet_poison]

I do know what rational and irrational numbers are.

You said calculators can't handle rational numbers. I was asking if you meant to say they can't handle irrational numbers.
