[mkgmap-dev] Splitter Error

From Chris Miller chris.miller at kbcfp.com on Wed Sep 9 13:33:00 BST 2009

Hi Paul,

I'd used Ralf's osm file as a test case to solve this problem, but seems 
like even that didn't go far enough. I have no idea why but the numbers in 
your file contain several digits more precision than a 64bit floating point 
number can even represent. I've added another check so that any digits beyond 
what is sane are now safely ignored. Sorry for the trouble and thanks for 
letting me know. It should be solid now but if you still have a problem please 
send through your test file and I'll take another look.


P> Sorry Chris but unless I've missed something then.....
