# & operator

Source: https://ref.dm-lang.org/operator/amp/

### Format
> `A & B`

### Returns
> The binary "and" of A and B.

A and B must be between 0 and 2\*\*24 - 1, giving an effective width of 24 bits.

If A and B are lists, the result is a list that contains only items that were in both lists, in the order of list A.

If A is an icon or /icon datum, it is blended with B which can be either a color or another icon. This is identical to the + operator. Transparent areas in either icon will be transparent in the result.
