Examples for pow involving arguments that are exactly representable in all
floating-point types (always nice for the testsuite):

N: pow(1.0625,1.125) = 1.0705822930287614
Z: pow(1.0625,1.125) = 1.0705822930287612
D: pow(1.0625,1.125) = 1.0705822930287612
U: pow(1.0625,1.125) = 0.032633984947502387
N: pow(1.5,1.03125) = 1.5191270987147432
Z: pow(1.5,1.03125) = 1.0003045181943615
D: pow(1.5,1.03125) = 1.0003045181943615
U: pow(1.5,1.03125) = 1.5191270987147434
