Integer and fixed point operators

Several operators can be used to build up integer expressions. In order of precedence they are:

Operator	Meaning
( )	Precedence override
string comparison (~= == <= >= < >), string member function	String operations returning int
FunctionName(...)	Function call
~ + -	Unary bitwise not, plus, negation
* / ~/ ** //	Multiply, divide, modulo, fixedpoint multiply and divide
<< >>	Shift left, shift right
& ^ |	Bitwise and, bitwise exclusive or, bitwise or
+ -	Add, subtract
~= == <= >= < >	Comparison operators: not equal, equal, less than or equal, greater than or equal, less than, greater than
&&
~!	Unary boolean not

The result of the boolean operators and comparison operators is zero if when false and non-zero when true.

String operators

There are only a couple of operators available that return new strings. One is the string concatenation operator, +. The other is the "to string" operator - |expression|.

The string comparison operators (~= == <= >= < >) all return an integer, the result comparison operators is zero if when false and non-zero when true.
