Here's a full-featured scientific calculator for your iPhone or iPod touch. It's really six calculators in one, with new button sets exposed by a tap on the tab bar. Features are important, but it's the little things that count, right? Little things like a design that looks like it belongs on your iPhone; big, easy to press buttons; a delete key in case you hit the wrong one; and picking up right where you left off if you are interrupted by a phone call--even in the middle of entering a number. Features: 1. Algebraic entry 2. Scientific calculations 3. Conversions for - Length - Area - Volume - Temperature - Mass - Speed 4. Logic calculator supporting base 2, 8, 10 and 16 5. 10 memory registers 6. Numbers range from about 1e-313 to 1e308 7. Displays 14 significant digits
