Geekulator for Geeks vs Regex Parse & Replace Dev Tool

Sometimes geeks need a special type of calculator to do special geek stuff. Geekulator is that calculator. It handles the most common integral base conversions as well as all those everyday bit-wise operations we're constantly goofing around with. It even does OSType (4-char code) conversions, although those aren't as common these days as they once were in Mac development. The style and layout is based on one of the most gorgeous calculators of its day, the Unisonic CB-14: Its clean style impressive, its buttons and switch sure and solid. Features: •Automatic display of binary, decimal, hex, and OSType. •Input switchable between binary, decimal, hex, and OSType. •Tappable binary bits. (Good luck hitting the right one with normal sized human fingers!) •Sign switch for choosing signed or unsigned integers in the decimal display. •The 4 common math operators, plus mod (%), a +/- button, and bitwise operators (and, or, xor, and not). •Bit shifting operators, both single shift or valued shift. •Choosable LED display colors. •Choosable LED fonts.
