I am using Composer XE for C/C++ (12.1 and 13) . I am trying to determine if the IEEE extended presicion (80 bits) and quad precision (128 bits) formats are supported in versions 12.1 or 13 of the C compiler.
I have been going over the manual but the only relevant information I ran into was one example using long double where the variable is called 80bit...
Should I assume long double in C translates to IEEE 80 bit extended precision format? Is quad (128 bits) supported? If yes, how? long long double?
