Description
Description
Based on the requirements we should support error type #Null.
Steps to reproduce
src/Cell.ts
/**
* Possible errors returned by our interpreter.
*/
export enum ErrorType {
/** Division by zero. */
DIV_BY_ZERO = 'DIV_BY_ZERO',
/** Unknown function name. */
NAME = 'NAME',
VALUE = 'VALUE',
NUM = 'NUM',
NA = 'NA',
/** Cyclic dependency. */
CYCLE = 'CYCLE',
/* Wrong address reference. */
REF = 'REF',
}

Research direction
Start in src/Cell.ts by reading ErrorType and then search for where its values are produced or handled. Compare the expected #Null behavior with the linked OpenFormula specification; done means the interpreter supports #Null consistently and the relevant existing tests pass.
