shiftleft
Bit shift to the left
Description
Shifts all bit values to the left. This has the effect of multiplying a number by a power of two, but is less expensive in computer time.
Arguments
initial-value[int]
optional
Sets an initial value for the number of bits by which to shift leftward.
Attributes

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

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'

'48'
'64'
'72'
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]: 0
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile[symbol]
You can override the default appearance of a user interface object by assigning a JavaScript file with code for painting the object. The file must be in the search path.
patching_rect[4 floats]: 0. 0. 100. 0.
Sets the position and size of the object in the patcher window.
position[2 floats]
write-only
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]: 0
Sets whether an object belongs to the patcher's presentation.
presentation_rect[4 floats]: 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]
write-only
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]
write-only
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 bit-shift with the numbers currently stored. If there is no argument, << initially holds 0 as the number of bits by which to shift.
int
In left inlet: All bits of the number, in binary form, are shifted to the left by a certain number of bits. The resulting number is sent out the outlet.
- input
[int]
(inlet1)
In right inlet: The number is stored as the number of bits to left-shift the number in the left inlet.
- amount-of-bitshift
[int]
float
See the int listing.
- input
[float]
set
Sets input to the object without causing output ( bang will output it).
- set-input
[int]
list
In left inlet: The first number is bit-shifted to the left by the number of bits specified by the second number.
- input
[int]
- shift-amount
[int]
Output
int
The number in the left inlet is bit-shifted to the left by a certain number of bits. The number of bits by which to shift is specified by the number in the right inlet. The output is the resulting bit-shifted number.
