Expense Report Calculation Discrepancies

The Expense Report calculation depends on Scale Configurations done by the user.

There are two scale fields "Scale" and "Extended Scale" in Administration-Data->Currencies Tab

Scale                 - No. of digits to display in UI after the decimal.
Extended scale - No. of digits after the decimal that can be used for Expense Calculations.
Even a single digit calculation may vary the results. So based on the requirements, these fields needs to be set accordingly.

For Example:

Entered Amount	Conversion Factor to $	Amount Rounded to 2 digits after decimal (Extended Scale = 2)	Amount Rounded to 5 digits after decimal (Extended Scale = 5)
440	0.14903	$ 65.57	$  65.57320
205	0.14903	$ 30.55	$  30.55115
945	0.14903	$ 140.83	$  140.83335
770	0.14903	$ 114.75	$   114.75310
120	0.14903	$ 17.88	$   17.88360
200	0.14903	$ 29.81	$   29.80600
	TOTAL:	$ 399.39	$ 399.40040
If Scale value is set to 2, the total amount calculated is rounded to 2 digits for display	Total rounded to 2 digits : (Scale = 2)	$ 399.39	$ 399.40

If you want the total calculated with the values rounded to 2, then set the Extended Scale value to 2.
