About HDBhelper - Calc 4 Devs
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)
Features:
- No Ads!
- Hardware Keyboard support (Build in, Bluetooth, USB, ...)
- Bit Length: 8bit, 16bit, 32bit
- Signed, Unsigned
- Type in Bin, Dec, Hex
- Endianness: MSB First (Big Endian), MSB Last (Little Endian), Reverse Little Endian (DIP-Switches etc.)
- Simulate Endianess errors
- Arithmetic operations: addition, subtraction, multiplication, division, modulu
- Bit operations: shifting, rolling, NOT, AND, OR, XOR, XNOR
- Three layouts: Simple, Advanced and Display
- Languages: English and German
- Long Press "Del/Clr" to Clear
- Long Press "-" to enter Negative Value
- Supporting Devices from very small (ldpi) to big (xhdpi) and Tablets with Android 3.2+ in portrait and landscape
- Display 8 Bit Values in ASCII
- Toggle Bits by tapping
- Copy to Clipboard

I was looking for a quick and easy hex calculator and this one wins by a long shot. One suggestion: Add an option to disable the toast messages. They were very informative at first, but a popup for every bit I toggle gets old fast!

Great work, thank you! Do you think it would be possible to implement the ability to paste contents?

I have used this app a lot while programming. The conversion and bit operations are very helpful. If I have one suggestion for an improvement, it would be adding hardware keyboard support. My tablet has a dock but the number keys 0-9 simply focus the actionbar. It would be nice if I could type in calculations with the keyboard, just as I am typing this review. Edit: I like the new logo. I finally understand what HDB stands for.

Has a few bugs with certain calculations that call into question the rest, but still a good conversion app.

Gr8 for hardwares that has dip switches using the reverse little Endian binary (switch 1 on far left) (Simplex fire alarm for example)

Try typing 255 in dec, look at binary conversion. This bug causes me to question the display of all other conversions. Great otherwise.

Really quick and handy tool, especially for those who work with component circuitry. I would just make the suggestion to change the icon to something more distinguishable.

This is the best calculator app for bin, hex, and dec I've used. For the people who are new to this, ensure you have the correct endian setting, it defaults to little-endian, which can be confusing. Thanks, dev!
