I've started a
thread in the old UK forum which deals with printing REAL10 (long double) numbers. There isn't a problem with the gcc under the Linux operating system, but under Windows the compiler output is only garbage. My suspicion was that this has to do with the windows libc, because the gcc must use it and the MS compilers don't support this data type.
But that seems not quiet right: surprisingly enough, with g++ (the C++ compiler of the gnu compiler collection) isn't such a problem. It handles REAL10 values correctly. I could figure out that during studying some C++ sources in Geneva. I won't publish that sources, but I've written a small test program which illustrates the point.
The program is tested under Windows 7 and Windows 8 (64 bit).
