Compare the fractional part, f, of the mixed number.If 0 < x <= 0.25 or 0.75 x < f <= 0.99... then remove f.
If 0.25 < f <= 0.75 then replace f by 0.5

Some people find it easier to add or subtract whole numbers but yes, you could round to the nearest half.
When rounding to the nearest whatever, half the number round up and half round down. → the numbers that round to 170000 to the nearest 10000 are 170000 ± (10000 ÷ 2) = 170000 ± 5000 However, if a number is exactly half way, the convention is to round them up, so the numbers in the range: 170000 - 5000 ≤ number < 170000 + 5000 → 165000 ≤ number < 175000 will round to 170000 to the nearest 10000 → smallest number is 165000 → biggest [whole] number is 175000 - 1 = 174999
Half of 10 is 5.So numbers in the range 800 ± 5 round to 800 to the nearest 10, except that numbers exactly half way round up. Thus all numbers greater than or equal to 800 - 5 round up to 800 and all numbers less than 800 + 5 round down to 800,That is all numbers greater than or equal to 795 and less than 805 will round to 800 to the nearest 10.

4.5 already is rounded to the nearest half.
