Re: intel decimal math library

the Intel math library has 3 types decimal32, decimal64 and decimal128
the decimal64 is easy to use in QB64 but for the decimal128 I had make a wrapper
Code: QB64: [Select]
  1. Type BID_UINT128
  5.  
  7.     Sub binary64_to_bid128 (result As BID_UINT128, x As Double, Byval rnd_mode~&, pfpsf~&)
