Public Review Comment from Steve Lay: https://lists.oasis-open.org/archives/odata-comment/201707/msg00002.html, see also ODATA-1091:

The idea of doing general type promotion to the largest integer type makes sense to me, if the result overflows Int64 then you’d get null (according to my proposal) which is freely castable to any of the integer types.

But I propose that Single operations that overflow Single results should be promoted to Double in a similar way.  The definition of cast will need to be modified to allow for the cast of a Double to Single with overflow resulting in INF (not a failed cast).  The proposed difference between the way integers and floating point numbers behave in this respect is precisely because the latter can represent INF.
