decimal float support for C++

2009-07-08 Thread Janis Johnson
I'm investigating support for decimal floating-point arithmetic in G++. GCC currently supports this functionality in C for several targets based on ISO/IEC TR 24732. The C support adds 3 new scalar types: _Decimal32, _Decimal64, and _Decimal128. With support for mangling those types and defining
