Of course.. If you type say 0.26 this gets translated to the closest
possible 16.16 number..you lose some bits. This is especially true with .f
numbers - all constants get translated to integer/fixed-point and then to
floating point in the blitz environment. This sux.:)
The 16.16x16.16 multiplication routine in blitz, however is very good and
accurate.
