Arguments

$type

string Name of the predefiend computation

Calculate vat included/excluded

Set cross-computation for vat included/excluded price:

$Computation = $this->get('computation');
$Computation->newVar('vat')->setDefault(23);
$Computation->newVar('price')->setFormula('priceVat/(100+vat)*100');
$Computation->newVar('priceVat')->setFormula('price*(100+vat)/100');

$Computation->setValue('vat', 24, false); // Prevent calculations (values missing).
$Computation->setValue('price',100);    // Triggers all calculations.
$computation->getValue('priceVat');     // --> 124

Using Field -object

If you set Field object as variable value, all changes made to variable are mirrored to Field:

$Computation->setValue('priceTotal',$Order->total);
$Computation->setValue('amount',4);
// $Order->total --> 496

Documentation

You can set title and description to computation and variables for printing documentation:

$Computation = $this->get('computation')
    ->setTitle('Count total')
    ->setDescription('Count total amount from amount and price');

$Total = $Computation->newVar('total')
    ->setFormula('amount*price')
    ->setDefault(0)
    ->setTitle('Total price')
    ->setDescription('Multiplies unit price with amount')
    ->setUnit('eur');

$Computation->renderDoc();

Computation types

Price

Counting vat, amount and rate for given price:

$Price = $this->get('computation','price')
    ->setValue('price',100)
    ->setValue('vat',24)
    ->setValue('amount',2)
    ->setValue('currencyRate', 0.988);

$Price->getValue('priceVat'); // --> 124
$Price->getValue('priceTotal'); // --> 200
$Price->getValue('basePriceTotalVat'); // --> 245,024
