Number conversion utility.


Developer website: Wincent

Hextrapolate is a flexible number conversion utility for programmers and other people who work with numbers in a digital setting. It converts, in real time, any number in any base representation from Base 2 (Binary) through to Base 36. Numbers can be arbitrarily large, limited only by the availability of system resources.

By default, the main window provides spaces for the entry and display of Hexadecimal, Decimal (Base 10), Octal (Base 8) and Binary representations, as well as multiple fields for ASCII (7-bit text), UTF-8 and UTF-16 text representations and two adjustable fields that can be used to display any base from Base 2 through to Base 36.

What's New

Version 2.0:
  • [Enhancement] Added extensive embedded help documentation to the application (also available online).
  • [Bugfix] Adding missing ellipsis in main menu.
  • [Note] Added Kagi as a payment option.
In addition to the changes made in the beta:
  • [Note] WinHex has now changed its name to Hextrapolate. The name change has taken place at the request of X-Ways Software Technology, makers of an existing product for Microsoft Windows which is also called "WinHex", has been under development since 1995, and has over 20,000 registered users (as of April 2007). To avoid confusion for users of the X-Ways software, Wincent has changed the name of its own product to Hextrapolate. The X-Ways WinHex website can be found here.
  • [Feature] In addition to the ASCII conversion offered in version 1.0, the new version adds UTF-8 and UTF-16 (Little Endian and Big Endian) options in a pop-up menu.
  • [Feature] Both kinds of pop-ups (text encoding and base) are now paired; this provides convenient any-to-any conversion without having to toggle settings.
  • [Feature] Byte and bit-count shown in the main window title bar.
  • [Enhancement] Number conversion infrastructure rewritten from scratch with a view to better performance.
  • [Enhancement] Hextrapolate is now a Universal Binary that will run natively on both Intel and PowerPC processors.
  • [Enhancement] Updated the GMP arbitrary precision arithmetic library used by Hextrapolate to version 4.2.1.
  • [Enhancement] Integrated WOTest unit testing framework.
  • [Enhancement] Can now enter leading zeros.
  • [Bugfix] No longer possible to "overflow" the text fields (formerly the ASCII field); previously entering a sufficiently large quantity of decimal digits could case the ASCII field to turn blank.
  • [Bugfix] Fixed leaking WOMPZWrapper objects.
  • [Note] The Hextrapolate disk image now shows basic installation instructions for a drag-and-drop install.
  • [Note] Enabled crash reporter functionality.
  • [Note] Bumped the minimum required Mac OS X version from 10.3 to 10.4.
  • [Note] Replaced "Registration feed paid" checkbox with a proper interface showing registered user email address and buttons for purchasing, registering, unregistering and recovering lost license codes.
