Float Math Operation¶
Performs common mathematical operations on floating-point numbers. Supports binary operations (add, subtract, multiply, divide, modulo, power) and unary operations (sqrt and abs applied to the first input). Includes safety checks for division/modulo by zero and square root of negative numbers.
Usage¶
Use this node whenever you need to compute a float result from one or two float inputs in a workflow. Select the desired operation and supply operands a and b. For unary operations (sqrt, abs), only the first operand a is used but both inputs must still be provided.
Inputs¶
| Field | Required | Type | Description | Example |
|---|---|---|---|---|
| a | True | FLOAT | First float operand. Used as the left-hand side for binary operations and as the operand for unary operations (sqrt, abs). Accepts values in the range [-1e10, 1e10]. | 9.0 |
| b | True | FLOAT | Second float operand. Used for binary operations (add, subtract, multiply, divide, modulo, power). Ignored for unary operations (sqrt, abs). Accepts values in the range [-1e10, 1e10]. | 3.0 |
| operation | True | ['add','subtract','multiply','divide','modulo','power','sqrt','abs'] | Mathematical operation to perform. Binary operations use both a and b. Unary operations (sqrt, abs) apply only to a. | divide |
Outputs¶
| Field | Type | Description | Example |
|---|---|---|---|
| result | FLOAT | The computed floating-point result of the selected operation. | 3.0 |
Important Notes¶
- Division by zero: If b is 0 during divide, the node returns 0.0 and logs a warning.
- Modulo by zero: If b is 0 during modulo, the node returns 0.0 and logs a warning.
- Square root domain: If a is negative for sqrt, the node returns 0.0 and logs a warning.
- Unary operations: For sqrt and abs, only a is used; b is ignored but still required.
- Value ranges: Inputs a and b accept values from -1e10 to 1e10 with step 0.001.
Troubleshooting¶
- Unexpected 0.0 result: Check if you divided or modulo by zero, or attempted sqrt on a negative number; these cases return 0.0 with a warning.
- Wrong result for unary operations: Ensure you're interpreting b correctly—b is ignored for sqrt and abs.
- Overflow or extreme values: If results seem off with very large magnitudes, confirm a and b fall within the accepted range [-1e10, 1e10].
- Unknown operation: If the operation string is outside the allowed set, the node returns 0.0 and logs a warning; verify the operation value.
