The rule that is taught in schools is that rounding is determined by the value of the next digit. If it is 4 or less you would simply remove all the digits after the point of rounding. If the digit is 5 or more, you remove all the digits after the point of rounding but also increase the final digit of the rounded number by 1.
Unfortunately, this method is flawed because it introduces a systematic bias in the way 5s are rounded.
0 does not need rounding;
1, 2, 3 and 4 should be rounded down;
6, 7, 8 and 9 should be rounded up.
The two main ways of rounding 5 is to ensure that the last "surviving" digit is always odd or always even. The IEEE 754 standard is to round to even.
