Many architectures do not support real, and therefore it should never be

Precision problems aside, I would personally insist that implicit
conversation from any sized int always be to float, not double, for
performance reasons (the whole point of a compiled language trying
to supersede C/C++).
On almost all platforms, float and double are the same speed.
Note that what we're discussing here is parameter passing of single
values; if it's part of an aggregate (array or struct), the issue
doesn't arise.
