Degree Minute Second to Decimal Degree.

This code was written so I can later use it as a function on some larger projects.

int main()

{



  double DEGREES;        //set degree variable

  double MINUTES;        //set minute variable

  double SECONDS;        //set second variable

  double SECONDS_TOTAL;  //set sum total seconds

  double DECIMAL;        //set decimal 

  double DEC_DEG;        //set decimal degree



  printf("enter a DMS type number\n\n"); 

 //ask for DMS #, to be replaced later by piping a # from another function.//



  scanf("%3lf%*1c%2lf%2lf", &DEGREES, &MINUTES, &SECONDS); 

   //Takes first string of numbers and assigns to DEGREES, takes colon found in NMEA sentance as a one charactor string and does not store it. Finally takes the rest of the numbers in groups of two so they can be converted to a base ten system.//




  printf("\n%3g--> Degrees \n", DEGREES);        //This are just  //

  printf("%g--> Minutes \n", MINUTES);           //showing the    //

  printf("%g--> Seconds \n", SECONDS);           //numbers entered//



  SECONDS_TOTAL = (MINUTES * 60) + SECONDS;      //Convert minutes to seconds

  DECIMAL = (SECONDS_TOTAL / 3600);              //total seconds out of hour(degree)

  DEC_DEG = (DEGREES + DECIMAL);                 //Starting degree plus seconds over hour



  // printf("Total Seconds %g\n", SECONDS_TOTAL);   //this code only used to troubleshooot

  // printf("Decimal remainder %g\n", DECIMAL);     //some rounding errors

  printf("Dec Degrees %g\n", DEC_DEG);           //Final answer.
