I don't know the answer to your question, but recommend you post your Main Page question on [[Talk:The Algorithm]] and/or [[Talk:Implementations]] to best get the attention of those who can answer it. -[[User:Robyn|Robyn]] 23:37, 2 April 2009 (UTC)

hey, did you solve the problem already?  What was the answer? I was curious. -[[User:Robyn|Robyn]] 00:52, 3 April 2009 (UTC)

Yup, crisis averted! Turns out, that a fractional hexadecimal number is different than just a hexadecimal number. The algorithm doesn't just prepend a 0 before the hexadecimal number that is generated by the MD5 hash, that 0 actually changes the number into a fractional hexadecimal number. So it turns a plain old integer hexadecimal number into a hexadecimal fraction and then converts that hexadecimal fraction into a decimal fraction. Since hex is in base 16 and decimal is base 10 fractions work a little differently. -[[User:Claribanter|Claribanter]] 00:04, 03 April 2009 (UTC)

Excellent. I assume you saw [[User:Shmoula|Vaclav's]] implementation? -[[User:Robyn|Robyn]] 01:17, 3 April 2009 (UTC)

I did find Vaclav's implementation today. Is Vaclav's geoANDhash application the same as geohashdroid? http://code.google.com/p/geohashdroid/ If they're not the same, then I guess we'll have three. I really just want to work on adding some features to the standard geohashing application as a project for a class. My team and I might be better off using some of the open source code available and building on that though. -[[User:Claribanter|Claribanter]] 00:34, 03 April 2009 (UTC)
