SIMPL+ operators perform functions between two or more variables. SIMPL+ 
operators consist of Arithmetic, Bitwise, and Rational Operators.

-

Negation

-X

Negate the value of X (2’s Complement of X).

*

Multiplication

X *Y

Multiply X by Y (signed arithmetic).

/

Unsigned Division

X / Y

Divide X by Y, truncates result (unsigned arithmetic).

S/

Signed Division

X S/ Y

Divide X by Y, truncates result (signed arithmetic).

MOD

Signed Modulo

X MOD Y

Remainder after dividing X by Y (signed arithmetic).

UMOD

Unsigned Modulo

X UMOD Y

Remainder after dividing X by Y (unsigned arithmetic). 
Only 2-Series Systems.

+

Addition

X + Y

Add the value of Y to X.

-

Subtraction

X - Y

Subtract the value of Y from X.

<<

Shift Left

X << Y

Shift X to the left by Y bits; 0 is Shifted in.

>>

Shift Right

X >> Y

Shift X to the right by Y bits; 0 is Shifted in.

{{

Rotate Left

X {{ Y

Rotate X to the left by Y bits; full 16 bits used. Same as 
RotateLeft().

}}

Rotate Right

X }} Y

Rotate X to the right by Y bits; full 16 bits used. Same as 
RotateRight().

NOT

1's Complement

NOT(X)

Change 0 bits to 1, 1 bits to 0.

&

Bitwise AND

X & Y

AND the bits of X with the bits of Y.

|

Bitwise OR

X | Y

OR the bits of X with the bits of Y.

^

Bitwise XOR

X ^ Y

XOR the bits of X with the bits of Y.

NOTE: For the Shift and Rotate operators, only the lower 5-bits of Y are used, giving 
values of Y ranging from 0 to 31. For example, if Y=600, the lower 5-bits equate to 
24. Rotating a 16-bit number through 16 positions gives the original number back. 
Therefore, for rotating 24, the result is equivalent to rotating through 8. Shifting 
greater than 16 will always give a 0 as a result.
