Float Math Operation¶
Performs common mathematical operations on floating-point numbers. Supports binary operations (add, subtract, multiply, divide, modulo, power) and unary operations on the first input (sqrt, abs). Includes safety checks for invalid cases like division/modulo by zero and square root of negative numbers, returning 0.0 in those cases.
Usage¶
Use this node when you need to compute a single floating-point result from one or two float inputs within a workflow. Typical use cases include parameter calculations, normalization steps, or building simple arithmetic pipelines. Choose the operation and provide inputs; for unary operations (sqrt, abs), only the first input is used.
Inputs¶
| Field | Required | Type | Description | Example |
|---|---|---|---|---|
| a | True | FLOAT | First float operand. Used as the base value for all operations; for sqrt and abs this is the only value used. | 9.0 |
| b | True | FLOAT | Second float operand. Used for binary operations (add, subtract, multiply, divide, modulo, power). Ignored for sqrt and abs. | 3.0 |
| operation | True | STRING (one of: add, subtract, multiply, divide, modulo, power, sqrt, abs) | Specifies which mathematical operation to perform. | divide |
Outputs¶
| Field | Type | Description | Example |
|---|---|---|---|
| result | FLOAT | The computed result of the selected mathematical operation. | 3.0 |
Important Notes¶
- Input ranges: a and b accept values between -1e10 and 1e10 with a step of 0.001.
- Unary operations: sqrt and abs only use input 'a'; 'b' is ignored.
- Division/modulo by zero: If b is 0 for divide or modulo, the node returns 0.0.
- Square root domain: If a is negative for sqrt, the node returns 0.0.
- Power operation: Large exponents may overflow or produce very large values; ensure inputs are within practical bounds.
- Unknown operation: If an unsupported operation is provided, the node returns 0.0.

Troubleshooting¶
- Result is 0.0 unexpectedly: Check if you attempted division/modulo by zero, sqrt of a negative number, or selected an invalid operation.
- Output seems unchanged for unary operations: Remember that sqrt and abs ignore 'b' and operate only on 'a'.
- Operation selection not available: Ensure the operation value is one of the allowed options: add, subtract, multiply, divide, modulo, power, sqrt, abs.
- Precision issues: Floating-point arithmetic can introduce rounding errors; consider rounding downstream if exact decimal representation is needed.
