How does one convert a number like 0.0101100101_{2} to a base-16 system? I know how to do for ex. 10001110_{2}, but the comma (or period confuses me)...
Conversion between binary and hex integers is pretty easy - each group of four binary digits, starting from the left, can be written as a single hex digit. Converting binary fractions is almost as easy. Starting at the "binary" point, each group of four binary digits represents a power of 1/16. The first four digits to the right of the point are 0101, or 5 in hex, and continue in the same pattern. The first hex digit represents sixteenths, the next represents 256th-s (1/(16^{2}), and so on.
