On linux x86_64 : real.sizeof == 16 but it looks like only the

Is there a way to know the real size of a real ?
The best I can think of is to use the mant_dig property which
returns the number of bits in the mantissa.

Thx for the proposal. I actually found this in std.math which
confirms this is indeed a possibility.
