Inventory Cost Calculations

Hello

I am wondering if anybody else is seeing these discrepancies and opinion about them. Here is the scenario:

Simple Stock Entry:
10 Units @ $1.00 Total Cost $10.00
10 Units @ $1.00 Total Cost $11.00

HOWEVER:
When using he following report syntax:
{REPORT COST DETAILS:[C.Name],C.Quantity.Sum,[([C.Cost]*[C.Quantity]).Sum]/[C.Quantity.Sum]}

[([C.Cost]*[C.Quantity]).Sum]/[C.Quantity.Sum]
The calculation of $21.00 / 20 Units evaluates to $1.07c but the result is $1.05c.

2 cents in not a problem but I have a calculation of $80.00 / 15 Units evaluates to $ 5.50 but the result is $5.33c which is 16 cents off? (Note: There is no other stock for this item on file.)

I thought it may be inline formatting but it clearly shows $1.07 so $5.50 is not a rounded figure.
Comments @emre?

Also as a side issue how to people enter cost of freight and other bits? Do you just add these total the Total Cost - divide by Quantity and then add onto the per Unit Cost?
