Add comment to examples about other containers working equally well.

fb835eb029 fix rounding errors 
- the direct predecessor/successor for 0.5/-0.5 was formerly wrongly
   rounded to 1.0/-1.0 rather than 0.0

 - integral numbers of the format 1xxxxxx1 filling mantissa completely
   were formerly rounded to the next integral away from zero
