Ono to funguje!<br>
Děkuji.<br>
<br>
Zkusil jsem to ověřit i praxí, že jsem vyvětral. A celkem to sedělo
i tím praktickým pokusem.<br>
<br>
Já si to A-Studio snad budu muset taky nainstalovat.<br>
<br>
Ještě jednou díky.<br>

Tak jsem si řekl, že se nakonečně naučím s tím Android Studiem a
Kotlíkem.<br>
První funkční výsledek:<br>

Není tam žádné řešení co je zadáno a co ne, prostě vždy vypočítá
všechno.<br>
Hlavně by to teda asi chtělo zjistit, jak se v Androidu pracuje s
registrem, nebo kam se ukládají nastavení, aby všechno nebylo
pokaždý default.<br>
<br>
Nevím zda jsou všechny výpočy správně, tak pro jistotu tady je ta
výpočetní část, prosím zkontrolovat:-)<br>
