Print the actual value of each function result that's expected to be exact, rather than merely emitting a NULL if it's not right. Although we print these with extra_float_digits = 3, we should not trust that the platform will produce a result visibly different from the expected value if it's off only in the last place; hence, also include comparisons against the exact values as before. This is a bit bulkier and uglier than the previous printout, but it will provide more information and be easier to interpret if there's a test failure. Discussion: <18241.1461073100@sss.pgh.pa.us>
