Advanced Math Operation¶
Performs a set of advanced mathematical operations on a number. Operations include absolute value, square root, cube root, factorial (of the integer part), and integer greatest common divisor (GCD) and least common multiple (LCM) with a second value. Returns a single floating-point result with sensible safeguards for invalid inputs.
Usage¶
Use this node when you need single-value advanced math operations within a pipeline, such as normalizing values (abs), computing roots, applying factorials for combinatorial logic, or working with integer relationships via GCD/LCM. Feed a numeric value and select the desired operation; provide the second_value only for GCD/LCM.
Inputs¶
| Field | Required | Type | Description | Example |
|---|---|---|---|---|
| value | True | FLOAT | Primary numeric input. Used by all operations. Interpreted as a real number; for factorial, GCD, and LCM the integer part of its absolute value is used internally. | 9.0 |
| operation | True | ENUM | Operation to perform. One of: abs, sqrt, cbrt, factorial, gcd, lcm. | sqrt |
| second_value | True | INT | Auxiliary integer used only for GCD and LCM. Ignored for other operations. Must be between 1 and 1000 inclusive. | 12 |
Outputs¶
| Field | Type | Description | Example |
|---|---|---|---|
| result | FLOAT | The result of the selected advanced operation. | 3.0 |
Important Notes¶
- Factorial uses the integer part of abs(value). Very large factorials are capped for safety; extremely large inputs will return a safe default.
- Square root on negative inputs is invalid and returns a safe default result.
- Cube root is computed as a real-valued root; unusual inputs may be clamped to a safe default if unsupported.
- GCD/LCM treat both inputs as non-negative integers (using the integer part). For LCM, if either integer is 0, the result is 0.
- second_value is only relevant for gcd and lcm; it is ignored for abs, sqrt, cbrt, and factorial.
Troubleshooting¶
- Result is 0.0 unexpectedly: Check if the operation has invalid inputs (e.g., sqrt of a negative number) or if the operation name is not one of the supported options.
- LCM/GCD seem off: Remember both numbers are coerced to non-negative integers using their integer parts; verify 'value' and 'second_value' after rounding/truncation.
- Factorial returns 0.0 or not as expected: Ensure 'value' is within a reasonable integer magnitude; factorial uses int(abs(value)) and extremely large values are limited for safety.
- No effect from second_value: second_value only applies to gcd and lcm operations; it is ignored for others.
