Question

What is the difference between irrational numbers and an integer?

Answer 1

Sorry, man, site went out when writing my reply.

Answer 2

NP i was having some problems as well.

Answer 3

Integers are numbers like -1, 0, 1, 2, 3... meaning they have a sure amount. irrational numbers are numbers like pi, or tau - they cannot be expressed as a ratio of integers.
This should explain it more: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&sqi=2&ved=0CB4QFjAA&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FIrrational_number&ei=8WhaVOGhGYrfoASNs4K4DA&usg=AFQjCNFde-OZo-37OIHgsu-GTZZWKg7Dpg

Answer 4

The difference between an irrational number and an integer is that an irrational number cannot be expressed as the ratio of two integers (any at all), and a rational number can.

1 is a ratio of two integers; think about why that is true. So is zero! And 9,000! Or 1/2, 1/50th, or 59/287ths. All of these are rational.

Irrational numbers, that, by not being able to be expressed as a ratio of two integers, are almost always (to my knowledge) going on forever, like Pi, or e.

Pi never ends. e never ends. And you cannot express either as a ratio of two integers.

Answer 5

Did you write all that?

Answer 6

Thank You

Answer 7

Yeah, lol, I can type quick.

Answer 8

Thanks for explaining that better than I did!

Answer 9

No problem, HailKK said exactly what was correct, too. No problem, man.

Answer 10

Can you answer my question? It's my first one, I know the answer I just wanted to be sure

Answer 11

And when I say "never ends", I don't mean infinitely big or anything, but its digits keep going on forever when calculated, e.g. Pi is 3.14...(infinitely many digits), e is something like 2.71...(infinitely many digits)

I can try.

Answer 12

OK thanks again
