(via an email discussion) VC8 compiler: definition mis-interpreted as a function declaration Posted by Microsoft on 2/6/2007 at 10:06 AM Basically this is a known problem with Visual C++ – we just don’t handle this style of initialization when pointers are involved. I have looked at this issue a couple of times and have always … Continue reading “It Proved Just Too Difficult”

Back when I was developing shiphandling simulator software, I ran into situations where it was necessary to convert decimal degrees to degrees, minutes, and seconds (for example, nautical types like to express latitude/longitude using degrees, minutes, and seconds while computers prefer decimal degrees).
Here's some C++ functions which handle the conversion between these two formats:
std::string DMS::DegreesMinutesSeconds(double ang, unsigned int num_dec_places = 2) std::string DMS::DegreesMinutesSecondsLat(double ang, unsigned int num_dec_places = 2) std::string DMS::DegreesMinutesSecondsLon(double ang, unsigned int num_dec_places = 2) double DMS::DecimalDegrees(const std::string& dms)
These are inline functions defined in the header file, dms.h:(more...)
