Well, then, what is the place where the constant should be truncated to what
its mode can represent?

Right at the start of the Tree dumps there seems to be a difference between
float and _Decimal32.  Float constants are printed in E-Notation while
_Decimal32 constants are just printed as integers (with the above value, not
verified with anything else).
