& Reference

Bitwise intersection of two numbers

&

Description

Performs a bit-by-bit AND of two numbers as expressed in binary. Outputs a number composed of all those bits which are 1 in both of the two numbers.

Examples

Nonzero bits shared by both numbers........ Can be used as an odd/even detector

Arguments

initial-value [int]

Optional

Sets an initial value to be AND-ed with a number received in the left inlet.

Attributes

Common Box Attributes

annotation [symbol]

Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.

background [int] (default: 0)

Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.

color [4 floats]

Sets the color for the object box outline.

fontface [int]

Sets the type style used by the object. The options are:

plain
bold
italic
bold italic Possible values:

0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'

fontname [symbol]

Sets the object's font.

fontsize [float]

Sets the object's font size (in points). Possible values:

'8'
'9'
'10'
'11'
'12'
'13'
'14'
'16'
'18'
'20'
'24'
'30'
'36'
'48'
'64'
'72'

hidden [int] (default: 0)

Toggles whether an object is hidden when the patcher is locked.

hint [symbol]

Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.

ignoreclick [int] (default: 0)

Toggles whether an object ignores mouse clicks in a locked patcher.

jspainterfile [symbol]

JS Painter File

patching_rect [4 floats] (default: 0. 0. 100. 0.)

Sets the position and size of the object in the patcher window.

position [2 floats]

g/s(set)

Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.

presentation [int] (default: 0)

Sets whether an object belongs to the patcher's presentation.

presentation_rect [4 floats] (default: 0. 0. 0. 0.)

Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.

rect [4 floats]

g/s(set)

Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).

size [2 floats]

g/s(set)

Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.

textcolor [4 floats]

Sets the color for the object's text in RGBA format.

textjustification [int]

Sets the justification for the object's text. Possible values:

0 = 'left'
1 = 'center'
2 = 'right'

varname [symbol]

Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.

Messages

bang

In left inlet: Performs the comparison with the numbers currently stored. If there is no argument, & initially holds 0 for comparison.

int

Arguments

input [int]
In left inlet: The number is compared, in binary form, with the number in the right inlet. The output is a number composed of those bits which are 1 in both numbers.

  (inlet1)

Arguments

comparison-number [int]
In right inlet: The number is stored for comparison with a number received in the left inlet.

float

Arguments

input [float]
Converted to int.

set

Arguments

set-input [int]
In left inlet: The word set followed by a number will set the input to the bitwise-and operation without causing output (a successive bang will output the result).

list

Arguments

input [number]
comparison-value [number]
In left inlet: Compares the first and second numbers bit-by-bit, and outputs a number composed of those bits which are 1 in both numbers.

Output

int

The two numbers received in the inlets are compared, one bit at a time. If a bit is 1 in both numbers, it will be 1 in the output number, otherwise it will be 0 in the output number.
