You Round up to the next higher number
Round up.
To round 6.59 to the nearest whole number, you look at the digit immediately to the right of the decimal point, which is 5. Since 5 is equal to or greater than 5, you round the whole number up by 1. Therefore, 6.59 rounded to the nearest whole number is 7.

If a coordinate is half way between a number, eg (2.3,74) then you round to the nearest whole number so it would be (2, 74) (round 2.5 to 3 not to 2, round 2.1 to 2 not 3 and round 2.7 to 3, this is because the number after the decimal place is either closer to one or the other)
I assume in your question you are asking what happens when a number is in between two whole numbers. E.G 4 and 5 the middle is 4.5 If you wanted to round this up to 1 significant figure or an integer/whole number the rule is that if in the middle you always round up to the highest number. In the case of the example the answer would be 5 if you were to round it up.
