So , hexadecimal is not the same EBCDIC ?
Data in the computer is stored in 8-bit long bytes. Hex is a way of
displaying the contents of the bytes as two characters representing
the value of the first and second set of 4 bits. EBCDIC is a mapping
of Glyphs into one of 256 values. Thus the glyph "1" is mapped to the
value 241 or X"F1".

The original floating-point hardware of the S/360 architecture is
hexadecimal, not binary. A normalized value may have up to three
leading binary zeros as a consequence. -- <not cent from sell> May
