Rukovanje praznih celija
Prije toga, praznih celija bili prisiljeni numerickih 0 u nekim kontekstima i na prazan string u drugima, osim u izravnom odnosu gdje je = A1 = 0 i = A1 = "" obje rezultirao je TRUE ako A1 je bio prazan. Praznina vrijeme je naslijedena dok se koristi, tako da = VLOOKUP (...)= 0 i = VLOOKUP (...)="" dati TRUE ako je pregledna rezultiralo praznoj celiji se vrati.
Jednostavan referenca na praznu celiju i dalje prikazuje kao brojcana 0, ali nije nužno i tip numericke viŔe, tako i usporedbe s radom referenciranje celija kao Ŕto se ocekivalo.
For the following examples, A1 contains a number, B1 is empty, C1 contains the reference to B1:
|
Case |
Formula |
Results and comments |
|---|---|---|
|
A1: 1 |
C1: =B1 |
Displays 0 |
|
=B1=0 |
||
|
=B1="" |
TRUE |
|
|
=C1=0 |
TRUE |
|
|
=C1="" |
TRUE (previously was FALSE) |
|
|
=ISNUMBER(B1) |
||
|
=ISNUMBER(C1) |
FALSE (previously was TRUE) |
|
|
=ISNUMBER(VLOOKUP(1;A1:C1;2)) |
FALSE (B1) |
|
|
=ISNUMBER(VLOOKUP(1;A1:C1;3)) |
FALSE (C1, previously was TRUE) |
|
|
=ISTEXT(B1) |
FALSE |
|
|
=ISTEXT(C1) |
TRUE |
|
|
=ISTEXT(VLOOKUP(1;A1:C1;2)) |
FALSE (B1, previously was TRUE) |
|
|
=ISTEXT(VLOOKUP(1;A1:C1;3)) |
FALSE (C1) |
|
|
=ISBLANK(B1) |
TRUE |
|
|
=ISBLANK(C1) |
TRUE |
|
|
=ISBLANK(VLOOKUP(1;A1:C1;2)) |
TRUE (B1, previously was FALSE) |
|
|
=ISBLANK(VLOOKUP(1;A1:C1;3)) |
FALSE (C1) |
Note that Microsoft Excel behaves different and always returns a number as the result of a reference to an empty cell or a formula cell with the result of an empty cell. For example:
|
Case |
Formula |
Results and comments |
|---|---|---|
|
A1: <Empty> |
B1: =A1 |
Displays 0, but is just a reference to an empty cell. |
|
=ISNUMBER(A1) |
FALSE |
|
|
=ISTEXT(A1) |
FALSE |
|
|
=A1=0 |
TRUE |
|
|
=A1="" |
TRUE |
|
|
=ISNUMBER(B1) |
FALSE (Microsoft Excel: TRUE) |
|
|
=ISTEXT(B1) |
FALSE |
|
|
=B1=0 |
TRUE |
|
|
=B1="" |
TRUE (Microsoft Excel: FALSE) |
|
|
C1: =VLOOKUP(...) with empty cell result |
displays empty (Microsoft Excel: displays 0) |
|
|
=ISNUMBER(VLOOKUP(...)) |
FALSE |
|
|
=ISTEXT(VLOOKUP(...)) |
FALSE |
|
|
=ISNUMBER(C1) |
FALSE (Microsoft Excel: TRUE) |
|
|
=ISTEXT(C1) |
FALSE |
