Hi Biterider!
uqword2dec and qword2dec are the same proc.
No problem with that. For sure I maked some other change at same time

A side note is that prefix r8 for REAL8 can be a complication. I used for years prefix R8_ in 32 bits, but in 64 bits there is R8 register, and perhaps I will begin to use prefix rf8_. An alternative prefix, f8_, could be confused with prefix f1_, etc I use for functions and functions constants.
Good luck finding the issue, I failed miserably
