Operation Formula Description
Addition A+B
Subtraction A-B
Multiplication AxB
Division A/B Takes value 1 when B=0: Error “ARGUMENT” is set.
Power A^B Takes value |A|^B, no error is set, when A<0.
Sign -A
Parenthesis (...) Calculates everything in parenthesis, then applies operators outside.

Procedure Formula Description
Less Takes value 1 when condition is true, otherwise takes value 0
Less or equal Takes value 1 when condition is true, otherwise takes value 0
Greater Takes value 1 when condition is true, otherwise takes value 0
Greater or equal Takes value 1 when condition is true, otherwise takes value 0
Equal A=B Takes value 1 when condition is true, otherwise takes value 0
Not equal Takes value 1 when condition is true, otherwise takes value 0
Logical Inversion !A Takes value 1 when A=0, otherwise takes value 0
Conditional A ? B : C Takes value C when A=0, otherwise takes value B
Exclusive Or A ^^ B Takes value 1 when either A=0 or B=0 (but not both), otherwise takes value 0
Logic or Takes value 0 when A=0 and B=0, otherwise takes value 1
Logic and A && B Takes value 0 when A=0 or B=0, otherwise takes value 1

Function Formula Description
Square root sqrt(A) Takes value when A<0: Error “ARGUMENT” is set takes value
Square sqr(A) A x A
Exponential function exp(A) e^A
Exponential function base 10 exd(A) 10^A
Natural logarithm ln(A) Takes values 0.0 when A<0: Error “ARGUMENT” is set
Logarithm base 10 log(A) Takes values 0.0 when A<0: Error “ARGUMENT” is set
