donchen Posted December 10, 2007 Share Posted December 10, 2007 Hi guys, I am using a Casio fx-570s Scientific Calculator. Any idea what is the simplest way to calculate the modular of a number ? eg, 10 mod 7 = 3 3 mod 7 = 3 All these are small numbers but what about in a case of 674967459 mod 34 ?

n_K Posted October 30, 2011 Share Posted October 30, 2011 afaik there's no remainder modulous on casio's, only the absolute modulous function. It's kinda easy anyway, number - (round down (<number>/<divider>) * divider) Link to comment Share on other sites More sharing options...
joddie191 Posted October 30, 2011 Share Posted October 30, 2011 With the calculator in integer mode (I forget what models can and cannot do this) use this formula: A - B * (A / B). Example: 674967459 mod 34 674967459 - 34 * (674967459 / 34) => 674967459 - 34 * 19851984 = 3 edit: ups beat to it by n_K Link to comment Share on other sites More sharing options...
