摘要：

One parameter deformation of function is given by means of convergent star product, where the deformation parameter varies in some domain of C. The deformed functions are called star functions. In this note, we discuss, as a simple case, a star product of functions of one variable, and then, the product becomes commutative and associative. Several concrete examples are given together with their basic identities.
