/**
* Adds a custom mathematical formula to the internal library.

* @param handler - A callback function that processes the input arguments
* (strings, numbers, booleans, or arrays of these) and returns a single value.
*/
addFormula: (name: string, handler: mathFunction) => void;type cellValue = string | number | boolean
type mathArgument = cellValue | cellValue[];
type mathFunction = (...x: mathArgument[]) => cellValue;| ### Parameters | ||
|
|
||
| - `name` - (*string*) required, the formula name (case-insensitive, stored as uppercase) | ||
| - `handler` - (*(...args: any[]) => any*) required, the function that computes the formula result. Receives the resolved cell values as arguments |
- replaced generic handler type with named type aliases (cellValue, mathArgument, mathFunction) - updated handler parameter description for clarity - fixed code comment capitalization to match project style
