\u00davod do funkce LET<\/h2>\n

Funkce LET v Microsoft Excel a Google Sheets umo\u017e\u0148uje efektivn\u00ed v\u00fdpo\u010dty ve vzorc\u00edch d\u00edky definov\u00e1n\u00ed prom\u011bnn\u00fdch p\u0159\u00edmo v r\u00e1mci funkce. Tato funkce redukuje redundanci v\u00fdpo\u010dt\u016f, \u010d\u00edm\u017e doch\u00e1z\u00ed k rychlej\u0161\u00edm a p\u0159ehledn\u011bj\u0161\u00edm v\u00fdsledk\u016fm. Umo\u017e\u0148uje vytvo\u0159it aliasy pro slo\u017eit\u00e9 v\u00fdrazy nebo konstanty, kter\u00e9 se pot\u00e9 mohou pou\u017e\u00edt v pr\u016fb\u011bhu v\u00fdpo\u010dtu.<\/p>\n

Syntaxe a p\u0159\u00edklady<\/h2>\n

Syntaxe funkce LET je n\u00e1sleduj\u00edc\u00ed:<\/p>\n

LET(n\u00e1zev1, n\u00e1zev1_hodnota, [n\u00e1zev2, n\u00e1zev2_hodnota, ...], v\u00fdpo\u010det) <\/code><\/pre>\n
    \n
  • n\u00e1zev1, n\u00e1zev2, …<\/b> – Prom\u011bnn\u00e9, kter\u00e9 chcete definovat.<\/li>\n
  • n\u00e1zev1_hodnota, n\u00e1zev2_hodnota, …<\/b> – Hodnoty p\u0159i\u0159azen\u00e9 t\u011bmto prom\u011bnn\u00fdm.<\/li>\n
  • v\u00fdpo\u010det<\/b> – Fin\u00e1ln\u00ed v\u00fdpo\u010det s vyu\u017eit\u00edm definovan\u00fdch prom\u011bnn\u00fdch.<\/li>\n<\/ul>\n
    P\u0159\u00edklad pou\u017eit\u00ed:<\/p>\n
    =LET(x, 10, y, 20, x+y) <\/code><\/pre>\n
    V tomto p\u0159\u00edkladu definujeme dv\u011b prom\u011bnn\u00e9, x<\/i> a y<\/i>, kde x = 10 a y = 20, abychom n\u00e1sledn\u011b vypo\u010detli jejich sou\u010det, co\u017e v\u00fdsledn\u011b d\u00e1 30.<\/p>\n
    Praktick\u00e9 aplikace funkce LET<\/h2>\n
    Aplikace pro sledov\u00e1n\u00ed rozpo\u010dtu<\/h2>\n
    P\u0159edstavte si, \u017ee spravujete tabulku s rozpo\u010dtov\u00fdmi polo\u017ekami a pot\u0159ebujete kalkulovat celkov\u00e9 n\u00e1klady po zahrnut\u00ed dan\u00ed a slev. S funkc\u00ed LET m\u016f\u017eete jednodu\u0161e definovat prom\u011bnn\u00e9 pro da\u0148ovou sazbu a slevu a pou\u017e\u00edt je pro konsolidovan\u00e9 v\u00fdpo\u010dty.<\/p>\n
    =LET(dan_sazba, 0.21, sleva, 0.1, SUM(C2:C10) * (1+dan_sazba) * (1-sleva)) <\/code><\/pre>\n
    Ve v\u00fd\u0161e uveden\u00e9m p\u0159\u00edkladu funkce LET zjednodu\u0161uje v\u00fdpo\u010det zaveden\u00edm prom\u011bnn\u00fdch pro da\u0148ovou sazbu (21%) a slevu (10%), co\u017e poskytuje p\u0159ehledn\u011bj\u0161\u00ed a srozumiteln\u011bj\u0161\u00ed vzorec.<\/p>\n
    V\u00fdpo\u010det pr\u016fm\u011brn\u00fdch hodnot<\/h2>\n
    LET je tak\u00e9 velmi u\u017eite\u010dn\u00e1 pro pr\u016fm\u011brov\u00e1n\u00ed hodnot podle specifick\u00fdch krit\u00e9ri\u00ed.<\/p>\n
    =LET(data, A2:A100, filtr, 50, PR\u016eM\u011aR.KDY\u017d(data, \">\"&filtr)) <\/code><\/pre>\n
    Zde LET definuje prom\u011bnnou data<\/i>, kter\u00e1 zahrnuje bu\u0148ky od A2 do A100, a prom\u011bnnou filtr<\/i>, kter\u00e1 nastavuje prah pro hodnoty vy\u0161\u0161\u00ed ne\u017e 50.
