Err... yes, in most cases(1). My mistake.

Of course, conversion to an integer format leaves no option for
representing infinity.

suggests that if the rounding mode is setup appropriately, it might not.
As I said, a lot of things got said in IEE754 that did not get implemented
in a standard way at the language standardization level.
