Abstract
We attempt to establish a calculus of the Moyal product treating the deformation parameter as a parameter moving in positive reals. We show strange phenomenas different from formal deformation quantization by studying the convergence of the parameter in computing the product of the exponential functions of the quadratic form. In the case of deformation quantization with the positive real parameters, the associativity for the Moyal product fails for a wider class of functions.
