alpha gives curious results as all values are exactly the same, which is quite
reasonnable, but may hide a bug too.
It gave (for 1 2 3 4 5):
N: exp(1) = 2.7182818284590451
Z: exp(1) = 2.7182818284590451
D: exp(1) = 2.7182818284590451
U: exp(1) = 2.7182818284590451
N: exp(2) = 7.3890560989306504
Z: exp(2) = 7.3890560989306504
D: exp(2) = 7.3890560989306504
U: exp(2) = 7.3890560989306504
N: exp(3) = 20.085536923187668
Z: exp(3) = 20.085536923187668
D: exp(3) = 20.085536923187668
U: exp(3) = 20.085536923187668
N: exp(4) = 54.598150033144236
Z: exp(4) = 54.598150033144236
D: exp(4) = 54.598150033144236
U: exp(4) = 54.598150033144236
N: exp(5) = 148.4131591025766
Z: exp(5) = 148.4131591025766
D: exp(5) = 148.4131591025766
