Operators
<exp1> + <exp2>: Addition
<exp1> - <exp2>: Subtraction
<exp1> * <exp2>: Multiplication
<exp1> / <exp2>: Division
<exp1> % <exp2>: Modulo (the remainder of an integer division operation)
<exp1> ^ <exp2>: <exp1> to the power of <exp2>
<exp1> < <exp2>: 1 if <exp1> is less than <exp2>, or 0 otherwise
<exp1> <= <exp2>: 1 if <exp1> is less than or equal to <exp2>, or 0 otherwise
<exp1> >= <exp2>: 1 if <exp1> is greater than or equal to <exp2>, or 0 otherwise
<exp1> > <exp2>: 1 if <exp1> is greater than <exp2>, or 0 otherwise
<exp1> == <exp2>: 1 if <exp1> is equal to <exp2>, or 0 otherwise
<exp1> != <exp2>: 1 if <exp1> is not equal to <exp2>, or 0 otherwise
<exp1> AND <exp2>: 1 if <exp1> is nonzero and <exp2> is nonzero, or 0 otherwise
<exp1> OR <exp2>: 1 if <exp1> is nonzero or <exp2> is nonzero, or 0 otherwise
<exp1> XOR <exp2>: 1 if <exp1> is nonzero and <exp2> is 0 or <exp1> is 0 and
<exp2> is nonzero, or 0 otherwise
NOT <exp>: 1 if <exp> is 0, 0 otherwise
- <exp>: Negation
