InfiniBase is the only app you'll need for converting numbers between bases. InfiniBase supports converting numbers between bases 2 through 36.
InfiniBase also has features that other conversion apps don't, including:
• Conversion of numbers of near infinite length*
• Automatic conversion as you type
• Customized keyboard for each number base
• A variety of sharing options, including printing and emailing
*InfiniBase uses the GMP Multi-Precision Library to allow conversion of numbers of any length. Obviously testing infinitely long numbers is not possible, however InfiniBase has been tested with converting some radically huge numbers.
