HEXw. Informat: UNIX

The HEXw. informat converts the hexadecimal representation of positive binary numbers to real floating-point binary values. The width value of the HEXw. informat determines whether the input represents an integer (fixed-point) or real (floating-point) binary number. When you specify a width of 1 through 15, the informat interprets the input hexadecimal as an integer binary number. When your specify 16 for the width value, the informat interprets the input hexadecimal as a floating-point value.
