=Error Message=
The user received an “Invalid Floating Point Operation” when creating or editing an order or estimate.
=Explanation of Error=
A “floating point number” is computer-speak for a decimal number. An “operation” in this case is a math operation. In practive, almost every “floating point operation” error you will get is a Division By Zero problem. (Others exist, but are extremely infrequent.)
This is almost always a case where Control is attempting to divide by a variable (usually quantity) that is zero. For example to get the unit cost they might take MaterialCost/Quantity but if Quantity is zero and the users doesn't consider this they will get either a “Division By Zero” or a “Floating Point Operation” error.
=Severity=
Normal. This affects the users ability to work this the affected product or any order/estimate containing it.
=Possible Root Cause(s)=
#1 Bad Quantity Formula
9/10/2011> Several users has the following formula as the formulat for Quantity in the product setup.
code_formatpascal|code format="pascal"
ParentVariableValue(Quantity, 0)
<code> For child line items, this worked fine. However, if that was promoted to or added as a top level item, it caused this error.
Resolution
Correct the affected formula to: code_formatpascal|code format="pascal"
ParentVariableValue(Quantity, 1)
<code> The following SQL can be used to identify all the products with this specific issue: code format="sql"
Select Item.ID as ProductID, Item.ItemName as Product, V.Formula
From Variable V
Join PricingPlan PP on PP.ID = V.PricingPlanID
Join CustomerGoodsItem Item on Item.ID = PP.GoodsItemID
Where Formula like '%ParentVariableValue(%,0)%'
and VariableName = 'Quantity'
