hyung-hwan 54855b9730 Fixed the printing issue of a long double value in MINGW32.
- The long double type in MINGW32 is 12 bytes while the double type is 8 bytes.
 - The compiled binary is linked against the Microsoft library.
 - In that library, both the long double and the double type are 8 bytes.
 - The code has been changed to use the double type if __MINGW32__ is defined.
