Allocate by Ratios¶
My company made a whopping profit of 5 cents, which has to be divided amongst myself (70%) and my investor (30%). Cents can’t be divided, so I can’t give 3.5 and 1.5 cents. If I round up, I get 4 cents, the investor gets 2, which means I need to conjure up an additional cent. Rounding down to 3 and 1 cent leaves me 1 cent.
Apart from re-investing that cent in the company, the best solution is to keep handing out the remainder until all money is spent. This is done by first calculating everybody’s share, rounded-down. Finally the remainder fractions are allocated one by one to the targets, the one with most lost due the rounding-down in previous step now coming first.
In other words:
use Money\Money; $profit = Money::EUR(5); list($my_cut, $investors_cut) = $profit->allocate([70, 30]); // $my_cut is 4 cents, $investors_cut is 1 cent // The order is important: list($investors_cut, $my_cut) = $profit->allocate([30, 70]); // $my_cut is 3 cents, $investors_cut is 2 cents
Allocate to N targets¶
An amount of money can be allocated to N targets using
$value = Money::EUR(800); // $8.00 $result = $value->allocateTo(3); // $result = [$2.67, $2.67, $2.66]
