Sorry, I misunderstood your point. You raised a good question.
We want strtod to read whatever printf might write, which the correct spec does. strtod allows the form "nan()" which printf doesn’t produce, but a program might produce "nan()" some other way. I suppose we could allow printf to produce "nan()", but I don’t see any value in doing it
