Action: modulus, ceiling, floor (rounding)

Mitchell,

Thanks for looking at this. If I knew how to patch, I would. I think it is fairly simple code because the PHP is fairly simple also.

$value = ceil()
$value = floor()
$value = x % y; where x is the value to take the modulus of and y is the mod. It would read x mod y.

thanks for the help. Also, nice meeting you in Denver.

wrote this last night. Feel free to use. Sorry if it isn't proper. Seemed to work for me.

I'll try to create a patch in a couple weeks, unless someone wants to beat me to it! ;-)

Hey Occucopy, I ended up making a custom module for actions. I don't know how to make patches, it is on my list of things to learn, I was also worried about making a patch and then having to recommit it every update.

Feel free and turn the above code into a patch if you're up to it...

Here you are. I think there are some custom commerce ones in there too, feel free to delete those.

@dbKern The actions are under actions-> custom actions -> Set Floor...

Reposting the module because it had specific commerce rules that would only work for my set up. Sorry about that.

Also, if anyone is super proficient at making patches. Please feel free to take and make this a patch, I'm pretty swamped and haven't had time to learn it...

Good to hear! :-)

Hey Mitchell,

WRT to use cases:

Modulus is a form of division. Where the number is divided and only produces the remainder. For example:
4 mod 2 = 0
5 mod 2 = 1
6 mod 2 = 0
6 mod 4 = 2 6/4 = 1 with a remainder of 2.

Ceiling: Rounds the number up to the integer regardless of the what side of the half it is on. 5.01 = 6

Floor: Rounds down to the integer regardless of what side of the half it is on. 5.99 = 5

Use Case for me was Shipping.
I have 4 box sizes that need to be accommodated for.

1 that holds 1 item = $12,
1 that holds 2 items = $15
1 that holds 3 items = $18
1 that holds 4 items = $20

The equation that you end up with is this: 12x + 8y + z = shipping cost

x = ceiling(total items/4)
y = floor(total items/4)
z = if (total items mod 4 = 1) = $3
else( total items mod 4= 2) = $5
else = 0

Hope this helps.

Mitchell, looked briefly at the post. I personally haven't looked into decimal rounding, so I cannot comment but I'm sure PHP would handle it appropriately and the rules framework seems like it would allow for anything PHP can do. I'll look at this over the weekend.

More math to insert:

            ),
          ),
          'provides' => array(
            'max_result'=> array(
              'type' => 'integer',

            ),
          ),
          'provides' => array(
            'min_result'=> array(
              'type' => 'integer',

          'group' => t('Custom Actions'),
          'parameter' => array(
            'input_a' => array(
              'type' =>'integer',
              'label' => t('Value 1'),
            ),
            'input_b' => array(
              'type' =>'integer',
              'label' => t('Value 2'),
            ),
          ),
          'provides' => array(
            'abs_result'=> array(
              'type' => 'integer',
              'label' => t('Value results'),
            ),
          ),
        ),

function max_number($input_a,$input_b){
  $vars = max($input_a, $input_b);
  return array('max_result' => $vars);
}

function min_number($input_a,$input_b){
  $vars = min($input_a, $input_b);
  return array('min_result' => $vars);
}
function abs_number($input_a,$input_b){
  $vars = abs($input_a, $input_b);
  return array('abs_result' => $vars);
}

This provides the maximum number between two values, the minimum and the absolute value of a number. Simple PHP really, but should help with calculations.

Please link to your new issue, so that can be solved and put to rest.

Once you have enabled the module, all you need to do is add an action and the rules will be listed. If you don't see them, flush all caches, if that fails something went wrong somewhere.

To add an offset before the calculation is done, go into data selection, select your variable and then add offset. To add it after, select an appropriate action to perform on the variable output.

Two things:
1) see your issue I have responded there.
2) From below: "Project issue numbers (ex. [#12345]) turn into links automatically."
