Radix Leaf app for iPhone and iPad

This application is a Positional notation (Hexadecimal,Binary, etc...) calculator.
Repeating a similar calculation is sometimes necessary. Full number input again and again is a nuisance. Dont you think its better if the calculation result comes only by different point correction? This application fulfills it.

It includes following functions these other normal calculators do not have.
・Fraction decimal and exponent of hexadecimal/.../binary (printf() %a) is available in input, display, calculation, conversion.
・Binary prefix unit of 1024^N (kibi, mebi, etc...) can be inputted.
・Long binary format that can cover hexadecimal whole digits.

Not all calculation finishes with getting the result. You often have the demand such as follows.
・To get results when the input is different. And the results of more various inputs.
・To get the input of the adjusted result.
This application watches a touch action to display number itself and does numerical value correction or input.
It makes simpler and easier the operation (correction, recomputation) like above cases.

(Spec)
・Other than usual Hexadecimal[16]/Octal[8]/Binary[2], Duodecimal[12]/Quinary[5]/Quaternary[4] are available for educational purpose.
・Logic 2 sheets (Add, Mul, AND, OR, XOR, NAND, NOR, XNOR, NOT, NEG, binary long display), Addition 1 sheet (5 items), Multiplication 1 sheet (5 items), 1 simple auxiliary total sheet (2 items total) are equipped.
・The touch action direct to the digit you want to change, makes numerical input or modify. It automatically calculates the results.
・Each positional notation base has independent keyboard.
・Copy / paste function of a sheet or each numeric.
・2 memories
・Every nemeric is switchable from 2 kind base.
・2 kind base has each separator position (3), and number format (3) of negative sign/complement/exponent.
・Selectable decimal point/separator (5).
・Landscape mode display (iPhone/iPod touch: one numeric enlargement / iPad: split screen)
・iPhone/iPod touch: 10-digit or 8-digit + 2digit-exponent display (Long Binary: 40-digit or 32-digit + 8digit-exponent is possible)
/ iPad: 14-digit or 12-digit + 2digit-exponent display (Long Binary: 56-digit or 48-digit + 8digit-exponent is possible)
・Rounding mode is always round down.
・Internal calculation operations: 16-digit decimal or fraction. Logic calculation is Hexadecimal. (For error minimising)
・Multitask (for i-Pad) and Handoff (2 units or more) of iOS are available.
