note 34823 modified in function.round by danbrown

The round() function may indeed work properly with half-values (eg. 1.5), but this little method will give you peace of mind. Add some "fuzz" to your function with a miniscule delta value. <?php $delta = 0.00001; $x = round($x+$delta); ?> This is fine, unless $x has a value of 1.49999 ... if you worried about that, use this method instead: <?php if(($x-floor($x))==0.5){ $x+=$delta; } $x = round($x); ?> you can change your "optimistic" delta into a "pessimistic" delta by subtracting instead of adding.
