bitand~

Bitwise and-operation of floating point signals

Description

Use the bitand~ object to perform a bitwise intersection (a bitwise "and") on two incoming floating-point signals as either raw 32-bit data or as integer values. The output is a floating-point signal composed of those bits which are 1 in both numbers.

Examples

Arguments

bitmask [int]

Optional

Sets the bitmask to be used by the bitand~ object. The default is 0 . An integer value can be used as a bitmask regardless of the mode; the binary representation of this integer is the bitmask.

operational-mode [int]

Optional

Specifies whether the floating-point signal or floating-point values will be processed as raw 32-bit floating-point values or converted to integer values for the bitwise operation. The modes of operation are listed below:

0: Treat both floating-point signal inputs as raw 32-bit values (default).
1: Convert both floating-point signal inputs to integer values.
2: Treat the floating-point signal in the left inlet as a raw 32-bit value
3: Convert the floating-point signal in the left inlet to an integer and treat the right input as a raw 32-bit value.

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.

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 [float]

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

textjustification [int]

Text Justification

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

int

Arguments

bitmask [int]
In right inlet: An integer value can be used as a bitmask when supplied to the right inlet of the bitand~ object, provided that the proper mode is set.

float

Arguments

bitmask [float]
In right inlet: A floating-point value can be used as a bitmask when supplied to the right inlet of the bitand~ object, provided that the proper mode is set.

bits

Arguments

bitmask [list]
In left inlet: The word bits , followed by a list containing 32 ones or zeros, specifies a bitmask to be used by bitand~. Alternately, a bitmask value can be set by using an int value in the right inlet.

mode

Arguments

behavioral-flag [int]
In left inlet: The word mode , followed by a zero or one, specifies whether the floating signal or floating-point values will be processed as a raw 32-bit floating-point value or converted to an integer value for the bitwise operation. The modes of operation are:

0: Treat both floating-point signal inputs as raw 32-bit values (default).
1: Convert both floating-point signal inputs to integer values.
2: Treat the floating-point signal in the left inlet as a raw 32-bit value and treat the value in the right inlet as an integer.
3 - Convert the floating-point signal in the left inlet to an integer and treat the right input as a raw 32-bit value.

Note: If you convert the floating-point signal input to an integer and then convert it back, the resulting floating-point value will retain only 24 bits of integer resolution.

signal

In left inlet: The floating-point signal is compared, in binary form, with the floating-point signal in the right inlet. The signal can be treated as either a floating-point signal or as an integer.
In right inlet: The floating-point signal to be compared with the signal in the left inlet. The signal can be treated as either a floating-point signal or as an integer.
The raw floating-point signal bit values are expressed in the following form:
<1 sign bit> <8 exponent bits> <23 mantissa bits>

Output

signal

The two floating-point signals or ints 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 floating-point signal.
