==~
Is equal to, comparison of two signals
Description
==~ outputs a 1 signal when the left input is equal to the right input and a 0 when it is not equal to the right input. The right input can be a signal or a float.
Arguments
initial-comparison-value[number]
optional
Sets an initial comparison value for the signal coming into the left inlet. 1 is sent out if the signal is equal to the argument; otherwise, 0 is sent out. If a signal is connected to the right inlet, the argument is ignored. If no argument is present, and no signal is connected to the right inlet, the initial value is 0 by default.
Attributes
fuzzy[atom]: 0.
When non-zero, an epsilon value to use for fuzzy floating-point comparison. Note that this isn't an absolute tolerance value, but is scaled to accommodate relative error for very large and very small values. The word epsilon can be used to denote the system FLT_EPSILON value.
When zero (default), standard floating-point comparison is used, which may cause apparently equal numbers to not be detected as such.
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]: 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'
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
int
In right inlet: A number to be used for comparison with the signal coming into the left inlet. If a signal is also connected to the right inlet, a float or int is ignored.
- input-comparison-value
[int]
float
In right inlet: A number to be used for comparison with the signal coming into the left inlet. If a signal is also connected to the right inlet, a float or int is ignored.
- input-comparison-value
[float]
signal
In left inlet: The signal is compared to a signal coming into the right inlet, or a constant value received in the right inlet. If it is equal to the value in the right inlet, 1 is sent out; otherwise, 0 is sent out.
In right inlet: The signal is used for comparison with the signal coming into the left inlet.
Output
signal
If the signal in the left inlet is equal to the value in the right inlet, 1 is sent out; otherwise, 0 is sent out.
