Operator Precedence
The order of precedence and associativity of operators in Eldo affect the evaluation of
expressions. For example, in the expression a=2+b*3, which happens first? the addition or the
multiplication? Expressions with higher-precedence operators are evaluated first.
Table 4-4 summarizes the precedence from highest to lowest and associativity (the order in
which the operands are evaluated) of Eldo operators. Where several operators appear together,
they have equal precedence and are evaluated according to their associativity.
Table 4-4. Operator Precedence
Operator Description Associativity
() function call left-to-right
! - logical NOT, unary negation right-to-left
** ^ power, power (synonym) left-to-right
* / multiply, divide left-to-right
+ - add, subtract left-to-right
> bitwise left shift, bitwise right shift left-to-right
< >= less than, less than or equal, greater than, left-to-right
greater than or equal
== != equal, not equal left-to-right
& bitwise AND left-to-right
| bitwise OR left-to-right
&& logical AND left-to-right
|| logical OR left-to-right
