When rounding to a specific place, take a look at the digit immediately to the right of the target, in this case, the tens place. If that digit is 4 or less, zero everything to the right of the target out. If that digit is 5 through 9, increase the target by one and zero everything to the right of it out. If the target is a 9, increasing it will turn it to zero and increase the digit to the left of the target by one.

The general rule of thumb is that anything less than .5 gets rounded down, and anything above .5 gets rounded up.

How exactly .5 is handled varies. Under one set of rules it's always rounded up; under another it's rounded towards the even number (which means it could be either up or down).
