SIMPL+ operators perform functions between two or more variables. SIMPL+
operators consist of Arithmetic, Bitwise, and Rational Operators.
NAME EXAMPLE
-X
X *Y
X / Y
X S/ Y
X MOD Y
X UMOD Y
X + Y
X - Y
NAME EXAMPLE
X << Y
X >> Y
X {{ Y
X }} Y
NOT(X)
X & Y
X | Y
X ^ 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.
EXPLANATION
Negate the value of X (2's Complement of X).
Multiply X by Y (signed arithmetic).
Divide X by Y, truncates result (unsigned arithmetic).
Divide X by Y, truncates result (signed arithmetic).
Remainder after dividing X by Y (signed arithmetic).
Remainder after dividing X by Y (unsigned arithmetic).
Only 2-Series Systems.
Add the value of Y to X.
Subtract the value of Y from X.
EXPLANATION
Shift X to the left by Y bits; 0 is Shifted in.
Shift X to the right by Y bits; 0 is Shifted in.
Rotate X to the left by Y bits; full 16 bits used. Same as
RotateLeft().
Rotate X to the right by Y bits; full 16 bits used. Same as
RotateRight().
Change 0 bits to 1, 1 bits to 0.
AND the bits of X with the bits of Y.
OR the bits of X with the bits of Y.
XOR the bits of X with the bits of Y.
