The rule for rounding is that if it is 5 or higher, round up. If it is 4 or lower, round down.

But...this depends where your rounding too.

If you wanted to round to the nearest whole number, you would get:

3

If you wanted to round to the tenths place, you would get:

2.9

If you wanted to round to the hundredths place, you would get:

2.90

If you wanted to round to the thousandths place, you would get:

2.897

If you wanted to round to the ten-thousandths place, you would get:

2.8974

NinjaDevo is correct, i'd just like to add one more thing. You will need to specify what you are rounding it to. For example, Round 4.8282 to the nearest tenth.

You still need to discuss the so called 'knock on effect'.

Suppose for example that you have the number 3.44445

Rounding to 4dp you get 3.4445, then to 3 dp 3.445, then to 2dp 3.45, then to 1dp 3.5, and finally to a whole number 4.

The 3.4445 is ok., but surely the others should be 3.444, 3.44, 3.4 and 3.

The implication would seem to be that when rounding, just the following digit should be considered, the ones after that ignored.
