To round any number, look at the digit to the right of the place you are rounding to. If the digit is 5 or more, change the digit in the place you are rounding to to the next higher digit. If the digit to the right of the place you are rounding to is less than 5, leave the digit in the place you are rounding to as it is. Change all digits to the right of the place you rounded to to zeros.

Some people find it easier to add or subtract whole numbers but yes, you could round to the nearest half.
to round, look at the digit immediately after the place value you are rounding to; thus, if you are rounding to hundreds, you look to the tens column. the digit "4" is in the tens column. numbers 4 and under round down; numbers 5 and higher round up. therefore, 147.32 rounded to the nearest hundred is 100

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 nearest tens and the nearest ones respectively. 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.
