a good hex/binary calculator

  • 772


Is there an obvious way of shifting numbers in the gcalc-tool using an operator, such as << or >>
Am I missing an obvious shortcut?
Say I want to simply perform (1<<20), how can I do that without the need to shift by 15 and then by 5 using the drop-down buttons?

Alternatively, is there a good hex/binary calculator that you would suggest specifically oriented at hex/binary operations?

Thanks!

    From what I have seen Gnome Calculator does not have keyboard shortcuts to those functions. Either way Qalculate lets you do exactly that.

    enter image description here

    To install either search it in Software Center or using terminal:

    $ sudo apt-get install qalculate-gtk

  2. BASH also supports bitwise operations like bitwise or:

    $ echo $((1|2|4|8|16))
31

    Hex and decimal:

    $ echo $((1|2|4|8|0x10|0x20))
63

    Zero-prefixed binary output (using BASH for the bitwise or, dc to output its binary, and printf to zero-prefix):

    $ printf "%08s" $(dc -e "2o  $((1|2|4|8|0x10|0x20)) p")
00111111

    Good for quick-and-dirty. man bash
