q-Pochhammer symbol.

$ wo 'QPochhammer[a, q, 0]'
1

The one-argument form is the Euler function QPochhammer[q] = QPochhammer[q, q].

$ wo 'QPochhammer[q]'
QPochhammer[q, q]

The two-argument form is the infinite product Product[1 - a q^k, {k, 0, Inf}], evaluated numerically when an argument is inexact.
