2.4 Arithmetic and Logical Operators

Basic operators in Bunao usually operate the way you'd expect them to. For users coming from outside the C style operator syntax (C, C++, Perl, Tcl, Java, etc), the most important exceptions are:

• to test equality, use the `==' operator (not `=')
• for logical and, use `&&', not `AND'
• for logical or, use `||', not `OR'

The full list of logical and arithmetic operators and their precedence values follows:

Symbol	Prec	Description
-	1	unary minus (like -3)
!	1	logical not
*	2	multiplication
/	2	division
%	2	modulus
+	3	addition
-	3	subtraction
<	5	less
>	5	greater
<=	5	less or equal
>=	5	greater or equal
==	6	equal
!=	6	not equal
&&	10	logical and
||	11	logical or

Bunao also supports the following operators:

~	1	bitwise not
<<	4	bitwise shift left
>>	4	bitwise shift right
&	7	bitwise and
^	8	bitwise xor
|	9	bitwise or
x?y:z	12	if x then y else z
