if

Function if

If testCondition evaluates to 0 then the result of falseExpr is returned, otherwise the result of trueExpr is returned. Note: both trueExpr and falseExpr are evaluated no matter what the result of testCondition is. You may want to consider using the [IF():] roll option instead.

Test condition notation:

• > for greater than
• < for less than
• >= for greater than or equal to
• <= for less than or equal to
• == for equal to - yes, you must use TWO equal signs to evaluate "is equal to"

If you are checking for a text string, place quotes around the text. You can find more information on these and other logical operations useful for the if function halfway down this page: http://rptools.net/doku.php?id=parser

Usage

[h: result = if(testCondition, trueExpr, falseCondition)]

Examples

[r: if(a>b, "A is larger than B", "A is not larger than B")]
[someProperty = if(variable>=1,20,"")]

Sets someProperty to 20 if variable is greater than or equal to 1, or makes it blank (but not empty) otherwise.

[someProperty = if(variable=="Text",1,0)]

Sets someProperty to 1 if variable contains the text string Text, 0 otherwise.

[someProperty = if(variable>0 && variable<20,1,0)]

Sets someProperty to 1 if variable is between 0 and 20.
