There is no widely accepted term for fractional binary numbers like 0.11001. A fractional decimal number like 0.427 is called a *decimal* or *decimal fraction*. A fractional binary number is called many things, including *binary fraction*, *binary decimal*, *binary expansion*, *bicimal*, *binimal*, *binary radix fraction*, and *binary fractional * (my term). In this article, I’m going to argue that **bicimal** should be the universal term.
