Opis funkcji obliczaj\u0105cych d\u0142ugo\u015b\u0107 ci\u0105gu tekstowego<\/h2>\n

Funkcje pozwalaj\u0105ce okre\u015bli\u0107 liczb\u0119 znak\u00f3w w ci\u0105gu tekstowym s\u0105 niezwykle przydatne do analizy danych tekstowych w arkuszach kalkulacyjnych, takich jak Microsoft Excel oraz Google Sheets. W Excelu u\u017cywamy funkcji LEN<\/code> (w polskiej wersji D\u0141<\/code>), natomiast LENB<\/code> (w polskim D\u0141.B<\/code>) jest stosowana do zliczania bajt\u00f3w w systemach dwubajtowych, co jest przydatne przede wszystkim dla j\u0119zyk\u00f3w azjatyckich.<\/p>\n

Funkcja D\u0141<\/code> zlicza wszystkie znaki w tek\u015bcie, w\u0142\u0105czaj\u0105c w to spacje. Z kolei D\u0141.B<\/code> wylicza ilo\u015b\u0107 bajt\u00f3w wykorzystywanych przez znaki (1 lub 2 bajty na znak).<\/p>\n

Sk\u0142adnia funkcji<\/h2>\n

Obie funkcje maj\u0105 bardzo prost\u0105 sk\u0142adni\u0119:<\/p>\n

=D\u0141(tekst) =D\u0141.B(tekst) <\/code><\/pre>\n

Przyk\u0142ady zastosowania<\/h2>\n
Przyk\u0142ad u\u017cycia funkcji D\u0141<\/code>:<\/p>\n
=D\u0141(\"Witaj \u015awiecie!\") \/\/ Zwraca 14, liczba znak\u00f3w \u0142\u0105cznie ze spacjami. <\/code><\/pre>\n
Przyk\u0142ad u\u017cycia funkcji D\u0141.B<\/code> w j\u0119zyku angielskim:<\/p>\n
=D\u0141.B(\"Hello World!\") \/\/ Zwraca 12, identycznie jak funkcja D\u0141, poniewa\u017c ka\u017cdy znak zajmuje 1 bajt. <\/code><\/pre>\n
Scenariusze zastosowa\u0144 praktycznych<\/h2>\n
    \n
  • Analiza wprowadzonych danych<\/b> – weryfikacja odpowiedniej liczby znak\u00f3w, np. w polu adresu e-mail.<\/li>\n
  • Struktura dokument\u00f3w<\/b> – kontrolowanie d\u0142ugo\u015bci opis\u00f3w, aby zachowa\u0107 sp\u00f3jno\u015b\u0107 w raportach.<\/li>\n<\/ul>\n
