The function from Felix Schwarz returns wrong results for values near 0. bccomp should be called
with param $scale.
function bcround ($number, $decimals, $precision) {
$precision_add = str_repeat("5",$precision);
if (bccomp($number,0, $decimals+$precision) > 0) {
return (bcadd (bcadd ($number,
"0.".str_repeat("0",$decimals).$precision_add, $decimals+$precision), 0,
$decimals));
}
else {
return (bcadd (bcsub ($number,
"0.".str_repeat("0",$decimals).$precision_add, $decimals+$precision), 0,
$decimals));
}
}
