Aakash Pandita Posted August 27, 2011 Share Posted August 27, 2011 Hello. Please tell me how to round off repeating numbers after decimal. For example, how to round off 0.6666666666...... would it be 6.5 or 6.7? and why? Link to comment Share on other sites More sharing options...
StringJunky Posted August 27, 2011 Share Posted August 27, 2011 (edited) When you round off you don't move the decimal point which you have done there...it will still be 'nought point something' unless you are rounding to the nearest whole number which would be 1 in that example's case. If the last digit you are interested in is 5 or higher you round up by 1 the digit before that one. So, 8.888 would be 8.89 Here's a more complete explanation on rounding off: http://www.mathsteacher.com.au/year7/ch06_decimals/14_round/off.htm Edited August 27, 2011 by StringJunky Link to comment Share on other sites More sharing options...
ajb Posted August 27, 2011 Share Posted August 27, 2011 If the last digit you are interested in is 5 or higher you round up by 1 the digit before that one. This is the convention we all follow. Link to comment Share on other sites More sharing options...

tomgwyther Posted August 28, 2011 Share Posted August 28, 2011 (edited) AFAIK, the recurring number has a dot or a line above it. i.e 1/3 expressed as a decimal is Edit: oh wait, that's not rounding off is it?

I thought the same way you did at first as well but checked myself. Link to comment Share on other sites More sharing options...
