If your compiler rounds, then you can simply add 0.5 to the FLOAT value
prior to converting it an INTEGER. You get the fractional part by 
converting the result back to FLOAT and subtracting it from the 
original FLOAT value.

Seems pretty simple to me (although it doesn't use any fancy Ada
features)  ;)

P.S., take care to check how your compiler rounds for numbers less
than zero and how it rounds (with the addition of 0.5) at the upper
and lower limits of the valid range.
