Rice flour

Rice flour (also rice powder) is a form of flour made from finely milled rice. It is distinct from rice starch, which is usually produced by steeping rice in lye. Rice flour is a particularly good substitute for wheat flour, which irritates the digestive system of some people. Rice flour is also used as a thickening agent in recipes that are refrigerated or frozen since it inhibits liquid separation.

Is this statement correct "is rice powder and rice flour the same"?
