How to translate |= operator from JavaScript to Delphi ?

Question

Today I faced an operator that I don't know what means in JavaScript, |= . Google doesn't help too much when you try to look for this "strange" characters. Someone knows what it means ? And How I convert it to Delphi ?

Thanks,

Answer 1

This

a |= b;

It is equal to this

a = a | b;

The operator | is called the bitwise OR operator and it

Returns a one in each bit position for which the corresponding bits of either or both operands are ones.

For further information regarding the bitwise operators in JavaScript, please have a look at Mozilla's JavaScript reference .

According to the Delphi documentation , I think that you are looking for the or operator:

a := a Or b;

Answer 2

It is bitwise or. In Delphi,

a := a or b;
