Hello! SOrry for this very basic question, but I'd like to know what 
happen during a simple casting between types with different size/delta. 
Example:

type one is delta 0.003 range -20.0 .. 200.0;
type two is digits 6 range -10.0 .. 400.0;
type three is delta 0.0023142 range -200.0.. 9999.0;

VAR1 : one := 23.0;
VAR2 : two;
VAR3 : three;

VAR2 := two ( VAR1 );
VAR3 := three (VAR1);

which values are in VAR2 and VAR3 and how ADA calculates it?

Why

VAR2 := two(23.0);

gives different value for VAR2 from

VAR2 := two ( VAR1 );   ??


Thanks in advance!!
