9. Operators

SS includes all of the numeric operators from C, with the same precedence, associativity, and meaning.

SS also includes operators ** for exponentiation, ^^ for logical XOR, and the logical assignment operators &&=, ^^=, and ||=. The keywords NOT, AND, XOR, and OR, case-insensitive, may also be used to represent the logical operators.

SS does not include the C array, structure, and pointer operators.

The operators are:

  ()            parentheses, (expr)
  ++            postfix increment, x++
  --            postfix decrement, x--
  ++            prefix increment, ++x
  --            prefix decrement, --x
  -             unary minus
  +             unary plus
  ~             bitwise NOT
  !             logical NOT
  NOT           logical NOT
  (int)         cast
  (long)        cast
  (double)      cast
  **            exponentiation, x**y == pow(x,y)
  *             multiplication
  /             division
  %             mod, x%y == fmod(x,y)
  +             addition
  -             subtraction
  <<            shift left, x<<y == x*2**y
  >>            shift right, x>>y == x/2**y
  <             less than
  <=            less than or equal
  >             greater than
  >=            greater than or equal
  ==            equal
  !=            not equal
  &             bitwise AND
  ^             bitwise XOR
  |             bitwise OR
  &&            logical AND
  AND           logical AND
  ^^            logical XOR
  XOR           logical XOR
  ||            logical OR
  OR            logical OR
  ?:            conditional operator, e1 ? e2 : e3
  =             assignment
  *=            multiplication assignment
  /=            division assignment
  %=            mod assignment
  +=            addition assignment
  -=            subtraction assignment
  <<=           shift left assignment
  >>=           shift right assignment
  &=            bitwise AND assignment
  ^=            bitwise XOR assignment
  |=            bitwise OR assignment
  &&=           logical AND assignment
  ^^=           logical XOR assignment
  ||=           logical OR assignment
  ,             comma operator

The bit shift operators <<, <<=, >>, and >>= are implemented for floating-point using ldexp() to adjust the binary exponent by the specified power of 2. For the other bitwise operators, the floating-point operands are converted to long integers to perform the operations.
