When calculating Inc GST Postage quotes they could be out by 1 cent due to rounding errors!
To fix this, internally, we have increased the number of decimal places used to store Ex GST Postage quotes from 2 decimal places to 4 decimal places. This eliminates the tiny rounding errors that occurred occasionally. For example, postage quotes
like $7.51 should really have been $7.50 and so on.
This brings postage quotes in line with the number of decimal places we use internally to store Ex GST pricing.
