Default Maths: why does 987654321 / 123456789 = 8.000000073

i have spent many time at work typing into my calculator stuff like this. anyone know why if you do 987654321 divided by 123456789 it comes to such an eerie number, so close to 8, but not quite?

Uhm.. Because 123456789 * 8 is almost equal to 987654321? Not trying to sound smug but that's all there is to it I think [img]/images/graemlins/smile.gif[/img]

eh, i'll explain a little. if you compare successive lines in the picture, you can see what is happening. it's a consequence of the fact that eight is two less than ten, the base of the decimal system. you would get a similar pattern with 6 in octal, or 14 in hexadecimal.

Consider 10/81 and 80/81 in decimal.

Also consider 1/9 in decimal, then square it.

Why are people trying to explain this with hexadecimals when this quote explains it entirely?

I'd rather someone tell my why cubes add up to squares. Using geomety, not algebra.

Scary.
