15 decimal C type



Greetings,

I am parsing some numbers with 15 decimal places, with:

fscanf(inf,"%lf,%lf", &xCor, &yCor);


with the input numbers:

569850.000000500003807,4900023.634829379618168


become rounded when output with:

fprintf (outf, "%lf,%lf\n", xCor, yCor);

to:

569850.000001,4900023.634829


I thought that I would want to use the "long double" ctype, but it apparently only supports 6 decimals? Or is fprintf doing the rounding?

Can anyone recommend a "C type" for 15 decimals on Darwin? I certainly would appreciate it!



Thanks,
