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.

• log(argument)
• sqrt(argument)
• abs(argument)
• round(argument)
• rand(argument)
• radians(argument)
• sin(argument)
• cos(argument)
• tan(argument)
• atan(argument)
• mod(a,b)

For example

Width=5+log($WordCount);

Datum=2*cos(radians($Angle));

From v4.5.2, the multiplication operator * may be used to multiply strings. thus, the expression

3*"xyz"

evaluates to:

xyzxyzxyz
