Engine	Documented	Live-tested	Verdict

LibreOffice Calc	Yes	Yes (24.2.7.2, 2026-07-04)	Quirk found

=COUNT(A1:A6) on LibreOffice Calc returned 3, but the documented/expected result is 2. A3 and A6 are blank, A2 is text, A4 is a boolean cell; only A1=10 and A5=20 are counted; MISMATCH vs expected: expected 2, got 3
=COUNT(A1:A1) on LibreOffice Calc returned 1, but the documented/expected result is 0. Per Microsoft's COUNT documentation, booleans in a referenced range are excluded from COUNT, unlike booleans typed directly as literal arguments; MISMATCH vs expected: expected 0, got 1

Formula	Description	Result	Expected	Verdict
=COUNT(A1:A6)	COUNT only counts numeric cells in a range; text, blanks, and booleans (when referenced via a range) are all excluded	3	2 A3 and A6 are blank, A2 is text, A4 is a boolean cell; only A1=10 and A5=20 are counted	Mismatch
=COUNT(A1:A1)	A boolean value referenced through a cell range is NOT counted by COUNT	1	0 Per Microsoft's COUNT documentation, booleans in a referenced range are excluded from COUNT, unlike booleans typed directly as literal arguments	Mismatch
=COUNT(1,TRUE)	Contrast with COUNT_boolean_in_range_excluded: a logical value typed directly into the argument list IS counted	2	2 Microsoft's COUNT docs: "Logical values and text representations of numbers that you type directly into the list of arguments are counted" - this differs from the same boolean sitting in a cell reference	Matched
=COUNT(A1:A5)	A range with no values at all counts as 0	0	0	Matched
