Most schools teach you to "round 5 upwards". This is wrong since it introduces an upward bias. See below for more details. The IEEE standard 754 is to round 5 up or down so that the new last digit is even. This is also "round five to even".
The schools method rounds 1, 2, 3 and 4 downwards and 5, 6, 7, 8 and 9 upwards, while 0 is not rounded. If the numbers at the rounding boundary are randomly distributed, you will round upwards 4/10 of the time and up 5/10 of the time: more upward rounding than downwards so creating a bias in results.

What is round to 1-digit accuracy?
That's the same as rounding to the greatest place. Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case the second greatest place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
