    Calc Lad

    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. Можно делить целые числа DIV с отображением остатка (MOD). Работает в ОС Linux.

    Woodland Potential Calculator

    Woodland Potential Calculator

    Woodland potential calculator GIS presentation application

    The Forestry Commission and Natural England commissioned a bespoke data collection and presentation tool for calculating the potential for increasing the extent of tree cover across the north west of England. The data was divided into sub-regions by landscape type using Natural England's Character Area classifications. The potential within each of these Character Areas was then estimated by working groups of local experts who were capable of making reasoned assessments of both the opportunities and constraints to woodland creation. Subsequently, this project was considerably extended and adopted as a national system. It is currently being used to compile the National Woodland Potential dataset for the whole of England.

    za tok!

    za tok!

    calculator helps you pay za your odnotarifniy tock with diapazony

    Калькулятор «За ток!» предназначен для расчета платежей за электроэнергию с учетом диапазонов. Только однотарифный расчет! После нажатия кнопки «Расчёт» производится расчет стоимости потребленной энергии и сохранение в ini-файл введенных значений: — цены за диапазоны; — текущий месяц (при повторном открытии программы он будет считаться прошлым месяцем); — последние показания счетчика (при повторном открытии программы они будут считаться показаниями за прошлый месяц). Предыдущий ini-файл сохраняется с тем же именем но с прибавкой к нему даты и времени сохранения. Если необходимо восстановить предыдущие значения, то просто удалите ini-файл za_tok.ini и удалите дату-время из имени копии оставив только название «za_tok.ini». Результат расчёта сохраняется в файл с именем «Itogo_20250305_093325-098.txt», где цифры это дата и время выполнения расчёта. Старые файлы переносятся в папку «arc».
