We are relatively new to using Ada and, whilst learning the language,
have used as a guideline the principle that there always seems to be
an Ada way of doing things. Whenever code we have written turns out
to be messy in Ada, subsequent analysis has revealed that a different,
better approach leads to a neater solution. Usually it is the data
modelling that is wrong.
Now we have encountered a problem, trivial by nature, which has us
baffled. The problem is simply that of obtaining the integer part of
a positive fixed-point value. We can find no simple way of achieving
this in Ada: use of numeric conversion leads to uncertainty regarding
the direction of rounding (ARM 4.6 p7).
No doubt we are going wrong again somewhere, but we cannot see where.
Maybe just wanting to examine the integer part of a fixed-point value
is against the principles of Ada real numbers.
Any ideas ?
Thanks in advance.
