Or, to avoid sprintf, you could use:

$rounded = int($unrounded + 0.5);

[download]

There are actually defined standards for rounding; to be absolutely pedantic, numbers which are exact odd multiples of ½ (i.e., (2n + 1)⁄/2) should round to the nearest odd number, so 4.5 and 5.5 should both round to 5

added in edit

salva's post reminded me that my fragment will only work for positive values of $unrounded. For negative values, one would have to subtract 0.5
