This is identical to the [[Elias gamma code]] of ''x''+1, allowing it to encode 0.<ref>{{cite book |last = Rupp |first = Markus |title = Video and Multimedia Transmissions over Cellular Networks: Analysis, Modelling and Optimization in Live 3G Mobile Networks |year = 2009 |publisher = Wiley |pages = 149 |url = http://books.google.com/books?id=H9hUBT-JvUoC&lpg=PA149&dq=Exponential-Golomb%20coding&pg=PA149#v=onepage&q=Exponential-Golomb%20coding&f=false }}</ref>

In other words, a non-positive integer ''x''≤0 is mapped to an even integer −2''x'', while a positive integer ''x''>0 is mapped to an odd integer 2''x''−1.
Exp-Golomb coding is also used in the [[Dirac (video compression format)|Dirac video codec]].<ref>{{cite web |title = Dirac Specification |url = http://diracvideo.org/download/specification/dirac-spec-latest.pdf |publisher = BBC |accessdate = 9 March 2011 |archiveurl = http://wayback.archive.org/web/20150503015104/http://diracvideo.org/download/specification/dirac-spec-latest.pdf |archivedate = 2015-05-03 }}</ref>
