FormulaDescriptionResultExpectedVerdict
=REPT("ab",3) Basic repetition ababab ababab Matched
=REPT("ab",0) number_times=0 returns an empty string, not an error
Microsoft docs: "If number_times is 0 (zero), REPT returns \"\" (empty text)." Source: https://support.microsoft.com/en-us/office/rept-function-04c4d778-e712-43b4-9c15-d656582bb061		 Matched
=REPT("ab",-1) A negative number_times is invalid -> #VALUE! #VALUE! #VALUE!
Documented behavior: REPT does not accept negative number_times and returns #VALUE! (per Microsoft's REPT reference and its documented remarks on the number_times argument)		 Matched
=REPT("ab",2.9) A non-integer number_times is truncated toward zero before repeating abab abab
Documented: "If number_times is not an integer, it is truncated."		 Matched
