About operators 193
Except for the strict equality (
===
) operator, the comparison operators compare strings only if
both operands are strings. If only one of the operands is a string, both operands convert to
numbers and perform a numeric comparison. For more information on strings and operators,
see
“About using operators with strings” on page 182 . For information on how order and
operator precedence affect your ActionScript, see “About operator precedence and
associativity” on page 179 .
About assignment operators
The assignment operators take two operands and assign a value to one operand based on the
value of the other operand. All of the operators in this table have equal precedence:
For information on using assignment operators, see “Using assignment operators”
