    Calc Lad

    Сalculator with a gold proportion calculation, memory work.

    Калькулятор "Лад" является безплатной программой ("Freeware") с открытым исходным кодом и распространяется по принципу "как есть" ("as is"). Может вычислять золотую пропорцию, проценты, сохранять значения в любую из 14 ячеек памяти, и извлекать эти значения из любой из 14 ячеек памяти, В историю вычислений можно дописывать значения словами. Можно сохранять историю вычислений в текстовый файл, и подгружать сохраненный текстовый файл в калькулятор. В версии 4.6 добавлена возможность узнать результат не только после нажатия =, но и после нажатия любого из знака + - * / При этом результат вычисления автоматически записывается в историю вычислений и переносится в переменную 1 и добавляется сразу знак который вы нажали, и вам только следует указать второе число. Если вы нажали символ квадратного корня или символ золотого сечения, то второе число не нужно добавлять-результат появляется сразу.
