We are planning to update it to the current Intel DFP library.
I thought that gcc implements its own DPF library according to IEEE 2008-754 standard and does not rely on Intel library. Please tell me if that's not the case, also what about decimal/dpd ( which does not rely on Intel library) ? is it based on another library ( IBM ) or gcc entirely implements it ? regards, Hesham > > -- > H.J.
