Mathematical operators

Actions and rules may use certain numeric operators. In all cases the argument may be a number or an expression that evaluates as a number.

• * (multiplication)
• + (addition)
• - (subtraction)
• / (division)
• == (equality)
• abs(argument)
• atan(argument)
• cos(argument)
• log(argument)
• mod(argumentA,argumentB)
• radians(argument)
• rand()
• round(argument)
• sin(argument)
• sqrt(argument)
• tan(argument)

For example

$Width=5+log($WordCount); 

$Datum=2*cos(radians($Angle)); 

Comparisons and equality tests are described separately under Basic Comparison Operators.
