HDBhelper

16進数、10進数とバイナリで簡単に計算および表示値。同時にすべて！

HDBHelper is the perfect Calculator for Developers! HDB stands for Hex Dec Bin, and it will help you a lot! ;-)

This app calculates as a Code would do. Example: An 8 Bit Unsigned Integer: 254+3=1

HDBHelper can display you up to 32bit long integers in Hexadecimal, Decimal and Binary at once. You can switch between signed and unsigned, even during the calculation. This way you will always know how your value changes due to Interpretation.

You can also simulate what happens if you mix up Endianess: If a Sender uses Big Endianess, the Receiver interprets it as Little Endianess. 192 (0x00C0) would get to 49152 (0xC000)
