Summary: Tax calculations problem for new orders.
Classification: Unclassified
Change sponsored?: ---
Product: Koha
Version: rel_3_6

OS/Version: All
Status: NEW
Severity: normal

When creating a new order, the automatic tax calculations may sometimes be
wrong because of loss of precision.
Example :
With gist=0, create a new order and put 18.99 into the "Vendor price" field.
The "Budgeted cost" and "Total" fields are automatically set to 18.98 when they
should be 19.99
The same happens with 16.99 .
Possible cause of the problem :
http://stackoverflow.com/questions/3730019/why-not-use-double-or-float-to-represent-currency
Here are some utility functions that could be used to correct the problem :
function to_Cents(val) {
return Math.round(val*100);
}
function to_Dollars(val) {
return (Math.round(val)/100).toFixed(2);
}
