Base Number Conversion Routines

screen-shot

Here are two routines that will take any decimal number and convert it to any number base between 2 and 36 and vice-versa. The first routine, ConvertDecToBaseN, takes the decimal number and the base to convert it to as parameters. If no base is supplied, then base 16 (hexadecmial) is assumed. The original author of this routine is Peter Rodriguez. I got his code from www.devx.com - it was a "Tip of the Day". In his tip, he encouraged the reader to derive a partner function that would bring his converted number back to base 10. So I accepted his challenge and wrote the second routine, ConvertBaseNToDec, which is modeled after his routine and takes the converted number and converted number's base as parameters and returns the decimal equivalent. If no base is supplied, then base 16 is assumed.

Note: these functions only work with whole numbers. They do not convert rational or irrational numbers correctly at this point.

The code comes with a sample project showing how the routines should be used.

  • Live Event Date: December 11, 2014 @ 1:00 p.m. ET / 10:00 a.m. PT Market pressures to move more quickly and develop innovative applications are forcing organizations to rethink how they develop and release applications. The combination of public clouds and physical back-end infrastructures are a means to get applications out faster. However, these hybrid solutions complicate DevOps adoption, with application delivery pipelines that span across complex hybrid cloud and non-cloud environments. Check out this …

  • On-demand Event Event Date: October 29, 2014 It's well understood how critical version control is for code. However, its importance to DevOps isn't always recognized. The 2014 DevOps Survey of Practice shows that one of the key predictors of DevOps success is putting all production environment artifacts into version control. In this webcast, Gene Kim discusses these survey findings and shares woeful tales of artifact management gone wrong! Gene also shares examples of how high-performing DevOps …
