This may be a stupid question and I don't know if I am even expre4ssing it correct, BUT Can anyone tell me or point me to some place that documents what the exact DECIMAL fixed-point value would be for the most accurate values of PI and E that can be stored in a binary128 data item? Would this just be (for PI) PI with 35 digits to the right of the decimal point? (I think that I am correct that any decimal item that can be stored in a binary128 item CAN be expressed exactly as a decimal fixed-point number - although the reverse is not true)
