Hello Derez,
Impressed by your brainwork!
Idea: what about adding bitwise.dll to perform Dec to Hex / Hex to Dec, etc. This will well occupy those two vacant buttons

One more:

Atnq (unlike Atn gets the correct quadrant)

Sub Atnq(x, y)
  z=Atan(x/y)
  if y < 0 Then z = z + cPI
  if y > 0 and x < 0 then z = z + cPI*2
  Return z
End Sub

Cheers
Robert
