“Always wanted to proof that Einstein was wrong? Are you the type of guy that freaks out when people say Pi=3.14, in stead of 3.141593? Then this is a place for you. A place for intelligent discussions regarding RL situations or discussions. Only for the smartest among us.”

Pi = 3.142 so I’m somewhere in-between.

Wonder whether it’s a UK thing or just my class that use an extra dp.  
 

One thing that annoys me is that 5 is rounded up, but 4.999~ is rounded down, when they're the same number.

you have to draw the line somewhere. anyway rounding >=5 up and 5< down is done because the sides are even. It also stops people having to check whether something’s recurring or not so its quicker. 

Na, I was taught in GCSE maths to use 3.142 too, not 3.14.
Must be UK curricilum.
or however you spell stupid words like that.

we always use 3.1415 in class

We use 3.142 in Aussie maths, HOWEVER, in adv. maths we leave it in exact form all the time

Sorry to resurrect the topic but.. its interesting...

Cant beat a good old bump, i remeber brodie used to bump topics about 3 months old!

...the good old days.

On a different forum, I used to bump neglected topics that had only 3 replies from 6 months ago, then watch how nobody realised, and they got loads and loads of replies...its weird, and then a moderator said i was "being evil" (that's a quote), so I stopped...

I use the symbol for pi. Never use the number. If I were to use the number, it would be "3.141..." to show that I'm leaving it as it is on the calculator to avoid rounding errors.

mmhmm.. like i said, Exact form.

yeah my priority is the exact form and then we were told to use the fraction 3 over 7 i think for sum reason

i think it is 22/7

22/7 ? 3/7? thats not exact form at all!! Ive never been told to put it in that way ever..

crazy Victorian education system lol

It is actually exact...considering pi is n e v e r e n d i n g, (forgot the term for that), a fraction is just as good as a symbol
