Comparator

Full Library / Math Operator / Logic / Comparator
Block Name: Comparator

• public class Comparator
• extends TypedAtomicActor

• Compare two double-valued inputs, and output the boolean result of the comparison. The exact comparison performed is given by the comparison attribute, which can take any of the following values:
• >: left > right
• >=: left >= right
• <: left < right
• <=: left <= right
• ==: left == right

The default is ">". The input ports are named left and right to indicate which side of the comparison operator their value appears on.

The tolerance parameter, which defaults to zero, defines an error tolerance. That is, the actor may produce true even if the specified test is not exactly satisfied, but rather is almost satisfied, within the specified tolerance.

Note that this actor will work with any data type that can be losslessly converted to doubles, such as integers.

left

public TypedIOPort left

• The left input port, which has type double.

right

public TypedIOPort right

• The right input port, which has type double.

output

public TypedIOPort output

• The output port, which has type boolean.

comparison

public StringAttribute comparison

• The comparison operator. This is a string-valued attribute that defaults to ">".

tolerance

public Parameter tolerance

• The tolerance for the comparison. This has type double, and defaults to 0.0.
