Scientific calculators are kind of like wildlife tags, clearly identifying certain individuals as nerds, who themselves view the tricorder-size devices as badges of honor and marks of distinction. While handheld scientific calculators will long find a cherished place on many a belt, smartphones and other powerful handheld devices are starting to target their lunch money, in part by ganging up with freeware like EasyFindSoft's Smart Scientific Calculator. It's a free, totally portable, fully featured scientific calculator for your desktop, laptop, or other Windows devices. It's HTML-based, uses Flash player, and offers a widget you can embed in your blog or Web page.
Smart Scientific Calculator is portable freeware that runs as soon as you click its program file, so you can save the download anywhere, such as the desktop or a USB drive. It opens a compact browser page with a realistic 3D-style image of a calculator displayed. Apart from links to the developer's and sponsor's Web pages, the only other controls access the widget tool and return the program to its Home page, which refreshes the view. Smart Scientific Calculator has a full set of buttons, including sine, cosine, tangent, and square root as well as memory and recall functions. We entered a few calculations, and Smart Scientific Calculator marked each keystroke with a sound. There doesn't seem to be any way inside the program to defeat the sound effects, beyond muting our sound card, nor did we find any settings other than those for Flash Player, and no Help file or documentation.
Still, Smart Scientific Calculator did everything we'd expect in a student-level instrument. As we noted, it's capable of advanced calculations, but some users may find they need something specific it lacks, and there are no customization options, though it does check for updates. For most users who need a scientific calculator, it's more than up to the job, especially since it's free.
