the following:
$int = 0.293847289472983;
echo $int ."\n";
echo round($int,2) . "\n";
echo round((int)$int,2) . "\n";
echo round((float)$int,2) . "\n";
echo round((double)$int,2) . "\n";
outputs on php 4.0.6:
0.29384728947298
0.29
0
0.29
0.29
however, using php 4.1.0, it outputs:
0.29384728947298299761570206101168878376483917236328125
0.289999999999999980015985556747182272374629974365234375
0
0.289999999999999980015985556747182272374629974365234375
0.289999999999999980015985556747182272374629974365234375
thus, be aware that round() should no longer be used for output. As previously commented, use
[s]printf() for that.
