/              Division

%            Remainder

+             Addition

-             Subtraction

<<           Shift Left (bit-wise)

>>           Shift Right (bit-wise)

>             Greater than

>=           Greater than or equal to

<             Less than

<=           Less than or equal to

==           Logical Equal to

!=            Not equal to

&             Bit-wise AND (valid for integer operands only)

^            Bit-wise Exclusive OR (valid for integer operands only)

|             Bit-wise OR (valid for integer operands only)

&&           AND

||            OR    (Valid for boolean integers or floating-point operands only)

Exp1?Exp2:Exp3    Conditional expression where Exp 1, 2 and 3 are math and/or logic expressions. Exp 1 is evaluated first. If it is non-zero (true), the tag uses the value of Exp 2 as its output. Otherwise, Exp 3 is used for the tag output.      

An example is C>0?A*B/C:1  If C is greater than 0, the tags value will be A*B/C.  If C is Not greater that 0, then output of the calculation is 1.
