Not 59.9999827? A lot of GIS data points are doubles. That means you have 
to mess around calculating epsilons since 59.999999 obviously isn't equal 
to 59.9999827.  There is an operation called 'snapping'. Essentially 
you're saying 'if the two points are 5 feet apart they're the same damn 
point.'

fundamentals/about-snapping.htm

It's embarrassing when an intended intersection really isn't connected. As 
far as shortest path routing is concerned it isn't routable.
