Advanced Math Operation¶
Performs a set of advanced mathematical operations on a single number, with optional use of a second integer for GCD/LCM. Supported operations include absolute value, square root, cube root, factorial (of the integer part), greatest common divisor, and least common multiple.
Usage¶
Use this node when you need single-input advanced math utilities or integer-based pair operations (GCD/LCM). Typical workflow: feed a numeric value, choose the operation, and provide the secondary integer only when using GCD or LCM. The node returns the result as a float.
Inputs¶
| Field | Required | Type | Description | Example |
|---|---|---|---|---|
| value | True | FLOAT | Primary numeric input. Used by all operations. For factorial/GCD/LCM, its absolute integer part is used internally. | 16.0 |
| operation | True | ["abs", "sqrt", "cbrt", "factorial", "gcd", "lcm"] | Selects the operation to perform. | sqrt |
| second_value | True | INT | Secondary integer used only for GCD and LCM. Ignored for other operations. | 12 |
Outputs¶
| Field | Type | Description | Example |
|---|---|---|---|
| result | FLOAT | The computed result of the selected operation. | 4.0 |
Important Notes¶
- Absolute value (abs): Returns the absolute value of 'value'.
- Square root (sqrt): Requires value >= 0. If value is negative, the node returns 0.0.
- Cube root (cbrt): Only supports non-negative inputs; negative inputs will result in 0.0.
- Factorial: Uses the absolute integer part of 'value' (floor of abs(value)). Values that would produce excessively large factorials (greater than 170!) return 0.0.
- GCD/LCM: Both operate on the absolute integer parts of 'value' and 'second_value'.
- LCM with zero: If the integer part of 'value' is 0, the LCM result is 0.
- Output type: Results are returned as FLOAT, even when the underlying operation is integer-based (factorial, gcd, lcm).
- Second value range: 'second_value' is constrained to integers between 1 and 1000.
Troubleshooting¶
- Got 0.0 unexpectedly: Check for invalid inputs: negative values for sqrt or cbrt, factorial too large (>170!), or other input constraints.
- GCD/LCM results seem off: Remember the node uses the absolute integer parts of inputs. Verify 'value' and 'second_value' after conversion to integers.
- LCM returned 0: This occurs if the integer part of 'value' is 0.
- Need cube root of a negative number: This node does not support negative cube roots; use a method that handles signed cube roots.
