Great - indeed,

 > sum [1.85, 5.95, -7.80]
8.881784197001252e-16
 > sum [1.85::Money, 5.95, -7.80]
0.00

I'm not yet sure these will do the best thing in all arithmetic, but it 
seems to be the right thing for now.

Yes, I will need to read these also. Perhaps first reading the integer and 
decimal digits as separate integers will help. I'm still exploring the 
number types.

Thanks for the tips!
