To Float (Boolean)

The To Float (Boolean) node in Magick converts a boolean value (true or false) into its corresponding floating-point representation. This node is useful when you need to use boolean values in mathematical operations or functions that expect floating-point inputs.

​
Inputs

  • a (boolean, default: false): The boolean value to be converted to a floating-point number.

​
Outputs

  • result (float): The floating-point representation of the input boolean value. true is converted to 1.0, and false is converted to 0.0.

​
Configuration

This node does not have any configuration options.

​
Usage

  1. Connect a node that produces a boolean output (such as a comparison node or a boolean constant node) to the a input of the To Float (Boolean) node.
  2. The node will output the corresponding floating-point value (1.0 for true, 0.0 for false) from the result output.
  3. Connect the result output to the input of another node that expects a floating-point value, such as a mathematical operation or function node.

​
Example

Suppose you have a boolean value indicating whether a user is logged in, and you want to use this value to calculate a score multiplier. You can use the To Float (Boolean) node to convert the boolean value to a floating-point number and then use it in a multiplication operation.
  1. Create a boolean constant node representing the user’s logged-in status (e.g., true for logged in, false for not logged in).
  2. Connect the boolean constant node to the a input of a To Float (Boolean) node.
  3. Create a float constant node with the base score multiplier value (e.g., 1.5).
  4. Connect the result output of the To Float (Boolean) node and the float constant node to the inputs of a Multiply node.
  5. The Multiply node will output the final score multiplier, which will be 1.5 if the user is logged in or 0.0 if the user is not logged in.

Best Practices

  • Use the To Float (Boolean) node when you need to use boolean values in mathematical operations or functions that expect floating-point inputs.
  • Be aware that the node converts true to 1.0 and false to 0.0. If you need different floating-point values for true and false, you can use a Select node or an If node to assign custom values based on the boolean input.

​
Common Issues

  • Make sure to connect a boolean value to the a input of the To Float (Boolean) node. Connecting other data types may lead to unexpected behavior or errors.
  • Remember that the node outputs 1.0 for true and 0.0 for false. If you require different output values, you’ll need to use additional nodes to modify the output accordingly.
