Name: bitAnd

Type: operator

Syntax: <number1> bitAnd <number2>

Summary:

Performs a "bitwise and" <operation> on the <binary> representation of

two numbers.

Introduced: 1.0

OS: mac, windows, linux, ios, android

Platforms: desktop, server, mobile

Example:

0 bitAnd 1 -- evaluates to 0

Example:

3 bitAnd 2 -- in binary: 11 bitAnd 10; evaluates to 10; converted to 2

Parameters:

number1:

The number1 and number2 are numbers, or expressions that evaluate to

numbers, between zero and 4,294,967,295 (2^32 - 1).

number2:

Description:

Use the <bitAnd> <operator> to operate directly on the <bit|bits> of two

numbers.

To perform the <bitAnd> <operation>, LiveCode first converts both

<operand|operands> to their <binary> equivalent, a string of ones and

zeroes. 1 is equivalent to true, and 0 is equivalent to false.

For each bit of <number1>, LiveCode performs an <and> <operation> with

the corresponding <bit> of <number2> to produce a result. A <bit> is 1

if the corresponding <bit|bits> of <number1> and <number2> are both 1.

Otherwise, the <bit> is 0.

Finally, the binary number thus created is converted back to decimal.
