For example:
venda de R$ 200,00 em 3x:
parc 1: 66,67
parc 2: 66,67
parc 3: 66,67
In addition to not making the change easier, it would be charging a penny more.
You would need a solution such as:
parc 1: 68,00
parc 2: 66,00
parcl 3: 66,00
To facilitate sales changes by the store, how to round the value of the decimal places for the first installment using Javascript?
Just divide 200 by 3 that gives 66.67, remove the decimal part, then 66. And then add to one of the plots the remainder of the division by 200 by 3.
Basic example:
<?php
$value = 200;
$prest = 3;
$div = (int) ($value / $prest);
$resto = $value % $prest;
$init = $prest-1;
$fin = $div+$resto;
echo "De {$value} tem de pagar {$init} prestações de {$div} e 1 prestação de {$fin}";
?>
