Operator

Description

+

addition

-

subtraction

*

multiplication

/

division

^

raise first operand to power of second operand

**

same as ^

AND

bitwise AND

OR

XOR

bitwise XOR

MAX

X MAX Y returns the larger of X and Y, i.e. equivalent to MAX(X,Y) in some other languages.

MIN

X MIN Y returns the smaller of X and Y, i.e. equivalent to MIN(X,Y) in some other languages.

=

Returns TRUE (-1) if the two operands are equal, else FALSE (0); not to be confused with = assignment operator

<> 

not equal (reverse of =)

#

not equal (same as <>)

> 

returns TRUE (-1) if the first operand is greater than the second

>=

returns TRUE (-1) if the first operand is greater than or equal to the second

< 

returns TRUE (-1) if the first operand is less than the second

<=

returns TRUE (-1) if the first operand is less than or equal to the second

MOD

X MOD Y returns the "modulo" of X relative to Y, i.e. the integer remainder after dividing Y into X. For example, a Julian date can be converted to the day of the week using JULDATE MOD 7 (returning a value in the range of 0-6, which you may then want to adjust according to what value you want to assign to what you consider the first day of the week).
