Divide the left operand by the right operand and assign the quotient to the left operand.

This is functionally equivalent to the expression:

anOperand1 = anOperand1 / anOperand2;

Although this is classified as an assignment operator, it is really a compound of an assignment and a multiplicative operator.

The associativity is from right to left.

Refer to the operator precedence topic for details of execution order.

The new value of anOperand1 is returned as a result of the expression.

Warnings:

• The operand to the left of the operator must be an LValue. That is, it should be able to take an assignment and store the value.
