percentage droplet

[snark]

the following script calculates a percentage:

Code: [Select]

<?php
function percent($num_amount, $num_total) {
$count1 = $num_amount / $num_total;
$count2 = $count1 * 100;
$count = number_format($count2, 0);
echo $count;
}
?>

which can be called by:

Code: [Select]

<?php percent(144, 12);?>

now I want to use this as a droplet which will app. be something like:
[[percentage?firstnumber=144&secondnumber=12]]

is there anyone who can help me here?

Droplet:  [percentage]

  [[percentage?basevalue=200&percentvalue=20&decimals=0]]

  20€ of  200€ are 10%

  [[percentage?basevalue=55&percentvalue=5&decimals=4]]

  5€ of 55€ are 9.0909%

The Droplet can handle integer and floatingpoint also
The number of decimals can be between 0 and 10

Code: (Droplet percentage) [Select]

<?php

  $basevalue  = isset($basevalue) ? (float)$basevalue : 0;
  if( !$basevalue ) return &#39;0&#39;;  // Division by zero protection
  $percentvalue = isset($percentvalue) ? (float)$percentvalue : 0;
  if( !$percentvalue ) return &#39;0&#39;;
  $decimals = isset($decimals) ? (intval($decimals) % 11) : 0;

  return  number_format( (( 100 * $percentvalue ) / $basevalue ), $decimals );

?>

Typo?

Code: [Select]

<?php

  $basevalue  = isset($basevalue) ? (float)$basevalue : 0;
  if( !$basevalue ) return &#39;0&#39;;  // Division by zero protection
  $percentvalue = isset($percentvalue) ? (float)$percenvalue : 0;
  if( !$percenvalue ) return &#39;0&#39;;
  $decimals = isset($decimals) ? (intval($decimals) % 11) : 0;

  return  number_format( (( 100 * $percentvalue ) / $basevalue ), $decimals );

?>

Code: [Select]

<?php

  $basevalue  = isset($basevalue) ? (float)$basevalue : 0;
  if( !$basevalue ) return &#39;0&#39;;  // Division by zero protection
  $percentvalue = isset($percentvalue) ? (float)$percentvalue : 0;
  if( !$percentvalue ) return &#39;0&#39;;
  $decimals = isset($decimals) ? (intval($decimals) % 11) : 0;

  return  number_format( (( 100 * $percentvalue ) / $basevalue ), $decimals );

?>twice the missing 't' in percentvalue

Didn't test it...
Have fun,
