What is the most portable and "right" way to do conversion from extended precision float (80-bit value, also known as "long double" in some compilers) to double (64-bit) in MSVC win32/win64?

MSVC currently (as of 2010) assumes that "long double" is "double" synonym.

So, title says it all. Why are floating point values so prolific in computer programming. Due to problems like rounding errors, and not being able to even accurately represent numbers such as 0.1, I really can't see how they got as far as they did. I understand that the computation is faster… >>> More

Python rather stupidly has a pragma directive in its include files that forces a link against python26_d.lib when the DEBUG preprocessor variable is defined. This is a problem because the python installer doesn't come with python26_d.lib! So I can't build applications in msvc in debug mode. If i temporarily… >>> More
