This appendix provides the syntax and examples for operators and expressions you can use in a calculation when creating a calculated field in a data object or report view.
It contains the following topics:
Table A-1 Operators Used in Calculated Fields
Operator | Function |
---|---|
+ (plus sign) |
Add |
- (minus sign) |
Subtract |
* (asterisk) |
Multiply |
/ (slash) |
Divide |
% (percent sign) |
Modulus |
() (parentheses) |
Parentheses determine the order of operations |
&& (double ampersand) |
Logical AND |
! (exclamation point) |
Logical NOT |
|| (double pipe) |
Logical OR |
== (double equal sign) |
Equality |
Field names containing any special characters, such as the operators listed in Table A-1 double quotation marks, or spaces, must be surrounded with curly braces {}. If field names contain only numbers, letters and underscores and begin with a letter or underscore they do not need curly braces. For example, if the field name is Sales, the correct way to enter this in a calculation is Sales. However, if the field name is Sales+Costs, the correct way to enter this in a calculation is {Sales+Costs}
.
Double quotes must be escaped with another set of double quotes if used inside double quotes. For example, Length("""Hello World, "" I said")
.

can accept one field parameter of type Integer
, Float
, or Decimal

can accept multiple field parameters of type String
, or string values may be entered.
