C++ functions to convert between decimal degrees and degrees, minutes, and seconds
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: [...]
C++ Functions to Evaluate Chebyshev Polynomials
Here’s some C++ functions which evaluate Chebyshev polynomials: T0(x): double T0(double x) ; T1(x): double T1(double x) ; T2(x): double T2(double x) ; Tn(x): double Tn(unsigned int n, double x) ; These are inline functions defined in the header file, chebyshev.h:
