What is the impact of the differing deltas in the following type
definitions :
type Long_Type is delta 180.0/2**31 range -180.0 .. 180.0;
for Long_Type'Small use 180.0/2**31;
for Long_Type'Size use 32;
and
type Long_Type is delta 256.0/2**31 range
-180.0 .. 180.0 - (180.0/2**31);
for Long_Type'Small use 180.0/2**31;
for Long_Type'Size use 32;
The first definition is the desired definition (and compiles using
Gnat). Unfortunately the 2nd one is as close as I can get using a
different compiler - one I am having to use, but not by choice!
I am really only interested in the effect on the attributes, operators
etc. of Long_type if the 2nd definition is used rather than 1st. Does
anyone know?
