Operators
Operators Overview
SIMPL+ operators perform functions between two or more variables. SIMPL+
operators consist of Arithmetic, Bitwise, and Rational Operators.
Arithmetic Operators
Bitwise Operators
OPERATOR NAME EXAMPLE EXPLANATION
- 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.
OPERATOR NAME EXAMPLE EXPLANATION
<< 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.
