float.init is not equal to 0.0f. In D FP points values are

By the way for strings it works, it's like the array case I
described in the first answer).
yes i guess i tested all/most types and know that float.init is
float.nan but why is nan true and not false?
because nan is not 0 and that the shortcut for float is
if (fpValue) <=> if (fpValue != 0)
if (!fpValue)<=> if (fpValue == 0)
There's no relation between the initializer and the shortcut.
It's not because for some values the shortcut matches to the
initializer that it must always be the case...But I admit I don't
know the exact rationale.
Does anyone know ?
