Hi, I am investigating the possibilities of using decimal floating point arithmetic with gcc (on Linux / x86_64 to be explicit). Are _Decimal32/_Decimal64/_Decimal128 available as builtin types without further action or do i as a DFP consumer have to issue the correspondent typedef/float/attributeS by myself (as is done in the testcases and the std::decimal headerS)? How do i convert _Decimal32/_Decimal64/_Decimal128/std::decimal from/to string/char* (and do cout/stdout I/O)? Can the (internal?) std::decimal method __getval (giving one of _Decimal32/_Decimal64/_Decimal128) be used by me as a user? Are there plans to add DFP support to glibc? Are there good examples out there showing the superiority of DFP arithmetic over ordinary (binary) FP arithmetic in the domain of monetary calculations?
Many thanks in advance Franz
