Advanced Base Converter & Calculator is an amazing tool for performing conversions and calculations on numbers with ALL bases ranging from 2 to 17. You can also work with fractional numbers.

The "Conversions" tab accepts 3 inputs :
1)The number you want to convert.
2)Base of the entered number (base here has range from 2 to 99).
3)The target base - the base to which you want to convert your number.

You can also tap on the back and forward buttons to view your previous calculations. Only unsigned numbers are accepted. Tap CONVERT and you have your answer.

The "Calculations" tab performs the 4 basic operations on numbers with any base ranging from 2 to 17.

A special feature of this app is that it can handle answers which end up as negative numbers. You can choose to express the answer in 3 forms :
1)Signed form - the normal form we represent negative numbers
2)Diminished base complement form - If the base of numbers was 2, then the answer will be represented in complement form of diminished base...1's complement
3)Base complement form - The answer is represented as complement with the base

The tab accepts 3 inputs :
1)First operand
2)Second operand
3)Base of operands - this is the base in which both the operands will be represented as well as the answer.

The back and forward buttons work similarly as in the previous tab. Tap clear in both the tabs to clear all the numbers.
