I discover specials results whith NProduct :
A[n_] := N[Product[1 + (-1)^k/Sqrt[k], {k, 2, n}]]
B[n_] := NProduct[1 + (-1)^k/Sqrt[k], {k, 2, n}]
{A[25], B[25]}
{0.30364, 0.303637}

{A[26], B[26]}
{0.36319, 0.455978}

We have also 1 + (-1)^26/Sqrt[26] = 1.196116135


I can't understand why there is a so huge difference between A[26] and B[26]

Do you have an idea ?
