Parsing through the individual digits of a double

hi,

i've been working on project display gps location , i'm having trouble trying data in right format.

the data retrived via    int latitude =  gps.latitude;  in format: 4042.6142

i wanting divide prints lcd in format: +40° 42.6142'


i have tried:

code: [select]

string lat =gps.latitude; //// = 4042.6142
 
    serial.print("+"); serial.print(lat[0]); serial.print(lat[1]);serial.print("\"");
    for(int = 0; i< 7; i++){
      serial.print(lat[i+2]);
    }
    serial.print("'");
   
but error:  conversion 'double' non-scalar type 'string' requested

which gps library using?
you state "the data retrived via    int latitude =  gps.latitude;  in format: 4042.6142"
the type int cannot store number decimal places (i.e. "4042.6142") without truncating it. need use double try use character array instead , use strtok function parse string.
try stay away string class past posts have shown problems memory usage , bugs. if can ythe output type(s) of gps library using easier help.
