10% tax calculation error #4813

Closed samsalway closed 7 years ago

I'm entering a purchase order, and 10% tax on $12.70 is being calculated as $1.28.

@samduff we will need to investigate this. Thanks for reporting it :+1:

May be tax rate defined in Item is different from 10 for one or more items. Please check "Show tax-breakup" under tax table for the details.

That does show the problem, the extra 1 cent comes from the accumulation of rounding errors. The item prices are $1.50, 0.78, 1.16, 1.47, 7.79.

I can't seem to replicate in my v8 dev instance.

@samduff can you please check and confirm if this issue is still replicating? Suggest you to make precision for the Currency field to 3 for more precise value in the decimal place. You can set precision for all the currency field at once from

Setup > Global Settings

If issue still prevails with 3 decimal places as well, feel free to re-open the issue.
