Funkce RAND (nebo N\u00c1H\u010c\u00cdSLO v \u010desk\u00fdch verz\u00edch Excel) poskytuje v Microsoft Excel a Google Sheets jednoduch\u00fd zp\u016fsob, jak generovat n\u00e1hodn\u00e9 \u010d\u00edslo mezi 0 a 1. Ka\u017ed\u00e9 \u010d\u00edslo v tomto intervalu m\u00e1 stejnou pravd\u011bpodobnost v\u00fdskytu d\u00edky rovnom\u011brn\u00e9mu rozd\u011blen\u00ed.<\/p>\n

V tomto p\u0159\u00edkladu funkce RAND()<\/code> generuje n\u00e1hodn\u00e9 \u010d\u00edslo mezi 0 a 1, kter\u00e9 se vyn\u00e1sob\u00ed \u0161esti a n\u00e1sledn\u011b se pou\u017eije funkce INT pro zaokrouhlen\u00ed na nejbli\u017e\u0161\u00ed ni\u017e\u0161\u00ed cel\u00e9 \u010d\u00edslo.
