Input of all number systems from binary system to hexadecimal system. Conversion of these number systems into one other and even up to the Base 36 numeral system. Addition, subtraction, multiplication and division of binary numerals and of all other number systems.
You can enter floating point numbers, too.

Addition, subtraction, muliplication and division is possible with these numbers. Conversion of floating point numbers into other number systems is very easy.

Through touching the red number you can easily select the desired number system. You can of course use the binary calculator as a normal calculator for decimal numbers. ;)

And this is how the binary calculator works:
Simply set a number for the source number system by touching the red left number. (For example, 8 for the octal system or 10 for the decimal system.)

The binary calculator now interprets all your data entry in these number systems.

If, for example, you would like to add the hexadecimal number A and BCF, the setting of the red left number is already sufficient.

Simply enter “A+BCF” and push “=”, and you have the desired outcome in the current selected hexadecimal system.

When you want to convert the current input to another number system, it is only the red right number that has to be touched. (For example, 16 for the hexadecimal system.)
Press just once on “Γ” and the calculator converts the given number in the desired system.

For a paid app it's quite lacking


I was excited to finally see a programming calculator app with floating point conversions, but this was a major letdown in almost every other regard - especially for a paid app - it's really lacking in some basic functionality. There are no settings whatsoever beyond selecting number base. Cannot choose signed or unsigned. No bitwise operations. No 2's compliment. No way to store values in memory. No way to choose bit size, i.e. 8, 16, 32, or 64 - useful for identifying overflow. No to mention the fact that one of the most useful tools for floating point values would be the ability to see the IEEE-754 floating point standard conversion.

Great little app.

Happy along the trails

The interface is not great--- but it does the job. It does math in any base you want. Very nice. Great for students who wish to check their math in beginning digital logic classes. It needs to be updated for iOS 11. In fact it is the only reason I haven't upgraded to iOS 11 yet.

Can't read the yellow color answer

Captain Kam

Majority of the time when answer is a long string of 0 and 1 it would display it it in tiny Yellow color which is impossible up read. Hence it would render this application useless.
Please Change the yellow to black or blur and keep the font size consistent.
