PHP Question

Remove useless zero digits from decimals in PHP

I'm trying to find a fast way to remove

zero decimals
from number values like this:

echo cleanNumber('125.00');
// 125

echo cleanNumber('966.70');
// 966.7

echo cleanNumber(844.011);
// 844.011


Does exists some optimized way to do that?

Answer

$num + 0 does the trick.

echo 125.00 + 0; // 125
echo '125.00' + 0; // 125
echo 966.70 + 0; // 966.7

Internally, this is equivalent to casting to float with (float)$num or floatval($num) but I find it simpler.
