    Amazing product. Anyone who does a wide range of recreational mathematics or non-negligible numeric work could die for a copy. The precision and performance are staggering and the variety of built-in function is startling when one considers the sheer volume of work it took to implement such a repertoire. Never mind the programming and design skills. That alone would be a hard act to follow, and in fact I do not offhand know of such any serious rival available online, but then there is the programmable facility as well. The programmability of the calculator should render the product enormously useful to engineers, statisticians and similar users who need heavy-duty arbitrary or repetitive calculation facilities at their fingertips. It could transform the value of either their desktops or their operating-system-capable tablets and similar devices. People who do not need thousands of digits of precision can specify any workaday modest precision that suits them, though there are plenty of applications such as cryptology that could benefit from multi-kilodigit calculation. I have not yet explored all the facilities of the product, and I never expect to, but for now I am gratified and breathless. I wish the creators success and reward with this or any future software they produce. In reviewing the rest of the user remarks, I see that someone suggested making it usable as a callable function by other software; personally I have no need for anything of the type, but it seems to me that it would be altogether reasonable to make it available as a callable utility for other software, but not as a freebie; anyone using it that way should be willing to pay for it non-optionally. I have not yet had occasion to assess the support in person, so I have just filled in a 5 as a place-holder to keep in line with the rest of my assessment (sorry about that!)

    This is a great project. When I look at its source code I realize how much effort you did. Thank you.

    Has replaced my non-windows 8 computers, calculator and is always available on win 8 comps. I will say; if your one of those people who post math problems on stuff like yahoo answers etc this probably isn't for you.
