'==, '!=

Synchronously compare two values for equality or inequality.

Syntax

'==
'!=

Options

None

Inlets

param1: The left inlet. Any value received via this inlet is compared to the value in the right inlet param2, and the result is sent via the outlet result.; Type: Changeable
param2: The right inlet. Any value received via this inlet compared to the value in the left inlet param1.; Type: Changeable

Outlets

result: '==: for scalar inputs, returns true if the values are equal, false if not.; '!=: for scalar inputs, returns true if the values are not equal, false if they are equal.; See comments for behavior with audio-sample inputs.; Type: Boolean or Samples

Comments

The equality and inequality operators accept inputs and initialization arguments of any numeric type (Integers, Floats, Doubles, Complex and DoubleComplex) as well as Strings. For scalar input, the operators return a true or false value.

If one of the arguments is an audio-sample type and the other is a numeric type, the equality operator returns a stream of audio-samples whose values are either 1 or 0 depending on whether the corresponding input sample is equal to the numeric argument. The inequality operator returns a similar result but with an output sample value of 1 whenever an input sample is unequal to the numeric argument. The relational operators do not support both parameters being audio samples.

These operators only output a result when new values have been received by both inlets. Thus, if a new value is received by param1, no result will be computed until a value is received by param2 as well. If this is not the behavior you want, try the the == or != operator instead.
