How to remove excess 0 after decimal point in php

1. Use "decimal + 0".

 <?php
echo '100.00' + 0 ."
";
echo '100.01000' + 0 ."
";
echo '100.10000' + 0 ."
";
?>

2. Use "floatval (decimal)".

 <?php
echo floatval('100.00')."
";
echo floatval('100.01000')."
";
echo floatval('100.10000')."
";
?>

3. Use "rtrim(rtrim(decimal,'0'),'.')".

 <?php
echo rtrim(rtrim('100.00', '0'), '.')."
";
echo rtrim(rtrim('100.01000', '0'), '.')."
";
echo rtrim(rtrim('100.10000', '0'), '.')."
";
?>

4. Use "preg_replace('/[.]$/','', preg_replace('/0+$/','', decimal)".

 Regular expression description:
/0+$/ removes the extra 0 at the end
/[.]$/ remove the trailing .
echo preg_replace('/[.]$/', '', preg_replace('/0+$/', '', '100.00'))."
";
echo preg_replace('/[.]$/', '', preg_replace('/0+$/', '', '100.1000'))."
";
echo preg_replace('/[.]$/', '', preg_replace('/0+$/', '', '100.010203000'))."
";
?>
