About

When two or more values are divided in an Izenda expression, the sql placed in the query is included in a case statement that sets the output to the string '#DIV/0' if the denominator is zero. This is to ensure that you do not encounter a divide by zero error. You can modify the output string by using a special custom format. If you would like to disable safe division in expressions entirely, you should set this AdHocSettings.UseSafeDivisionInExpressions to false. Note that this only disables safe division in expressions, and not elsewhere in the Izenda reporting environment.

Default Value: True
