A question for compiler writers that support decimal floating point (DFP).
What value and quantum exponent do you give a static decimal floating
point variable that gets the default initialization?
6.7.9 Initialization, paragraph 10, has (in part):
If an object that has static or thread storage duration is not
initialized explicitly, then: ...
if it has arithmetic type, it is initialized to (positive or unsigned) zero;
static _Decimal64 x; /* zero with what exponent? */
