There is no online help or documentation on this. It is axiomatic that the meaning of logical operators is assumed. For instance:

abs(A) = returns the absolute value of a number

avedev() = average deviation

***
floor(A)= The floor function of a real number x, sometimes called the greatest integer or entire function

***
exp(A,B) = Exponent of a number
fact(A)= Factorial of a number
***

One might desire to 1) take the average deviation of vacancies of X number of floors, or 2) know what the value of X to the 2 power would be in a report because the floor space or the head count might grow from 20 to 400. That would be exp(20,2) = 400. This gives the mathematically minded the means of providing mathematical calculations and reporting on them.
