Manexu de caxelles baleres
Primeramente, les caxelles baleres taben forzaes al númberu 0 en dellos contestos y a cadenes baleres n'otros, sacante en comparances direutes onde =A1=0 y =A1="" dambes resultaben en VERDADERU si A1 taba balera. Agora la cualidá de baleru heredar hasta que seya utilizada, asina ye que dambos =BUSCARV(...)=0 y =BUSCARV(...)="" dan VERDADERU si la resultancia de la busca devuelve una caxella balera.
Una simple referencia pa una caxella balera entá se visualiza como un númberu 0 pero nun ye necesariamente de tipu numbéricu, de cuenta que les comparances con referencia a la caxella funcionen como s'espera.

Note que Microsoft Excel pórtase distintu y siempres devuelve un númberu como la resultancia d'una referencia pa una caxella balera o una fórmula na caxella cola resultancia d'una caxella balera. Por exemplu:
|
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) |
