== Reference

Compare numbers for equal-to condition

==

Description

Compares two values to see if one value is equal to a second. Outputs a 1 if the number is equal to the comparison-number or 0 if it is not.

Examples

The numbers are equal...... The numbers are not equal..... Using == 0 as a logical 'not'

Arguments

comparison-value [int or float]

Optional

Sets the initial value, to be compared with a number received in the left inlet. A float argument forces a float comparison.

Attributes

fuzzy [atom] (default: 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.

The fuzzy attribute is only available in floating-point mode (when the object is instantiated with a floating-point argument).

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 with the number in the right inlet. If the two numbers are equal, == outputs 1. If they are not equal == outputs 0.

  (inlet1)

Arguments

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

float

Arguments

input [float]
Converted to int before comparison, unless == has a float argument.

set

Arguments

input [int]
Sets the number to be compared without causing output (bang will output it).

list

Arguments

input [number]
comparison-value [number]
In left inlet: Compares first and second number, outputs 1 if they are equal, 0 if they are not equal.

Output

int

1 if the numbers in the inlets are equal, 0 if they are not equal.
