[Dev-C++] RES: Reading and printing long double values

[André M. B. <and...@su...>]

   But MigGW does this distinction.

   Please try:
      printf(sizeof(double))      and
      printf(sizeof(long double))

   Does anybody know who wrote a printf or
a full stdio.h (fprintf, sprintf, etc) which
supports long doubles for MingGW?

Regards
André

MinGW is using the M$ libraries, so to my knowledge it isn't possible to
print a long double using printf().

Note that M$ does not distinguish between double and long double, so they
don't have a need for a long double formatting prefix.
