Math Subtract Float

The Math Subtract Float node performs subtraction on two floating-point numbers. It takes two input values, subtracts the second value from the first, and outputs the result.

​
Inputs

  1. a (float, default: 0): The first value in the subtraction operation.
  2. b (float, default: 0): The second value in the subtraction operation, which will be subtracted from a.

​
Outputs

  1. result (float): The result of subtracting b from a.

​
Configuration

This node has no additional configuration options.

​
Usage

To use the Math Subtract Float node:
  1. Add the Math Subtract Float node to your spell.
  2. Connect the a input to the first value you want to subtract from.
  3. Connect the b input to the value you want to subtract.
  4. The result output will contain the result of the subtraction operation.

​
Example

Here’s an example of how to use the Math Subtract Float node in a spell: 
1. Add a Trigger node and set it to "On App Start".
2. Add a Math Subtract Float node.
3. Add two Number nodes and set their values to 10.5 and 3.7.
4. Connect the first Number node to the `a` input of the Math Subtract Float node.
5. Connect the second Number node to the `b` input of the Math Subtract Float node.
6. Add a Debug Log node and connect the `result` output of the Math Subtract Float node to its `message` input.
7. Run the spell.
The Debug Log will output the result of 10.5 - 3.7, which is 6.8.

​
Best Practices

  • Ensure that the input values are valid floating-point numbers. Non-numeric inputs may cause unexpected behavior.
  • Remember that the order of inputs matters: a is the value being subtracted from, and b is the value being subtracted.

​
Common Issues

  • If either input is not a valid floating-point number, the node may output NaN (Not a Number) or an unexpected result.
  • Be cautious when subtracting very large or very small numbers, as floating-point precision limitations may affect the accuracy of the result.
