it is diffucult to view numbers as there is a conversion from the numerical
representation (ieee) vs the ASCII that you can see.  That is my point.  The
representation should be the SAME as the storage, then the person creating the
record can control what is there: what you see is what you get.  To try this
look at the internal representation of the number 50.  It is stored as a number
other that 50 times a binary exponent of 32 or 64.  The number can be very close
to a 50, but it cannot be 50.  If you want a 50, the number should be represented
as a decimal witha power of 10 exponent, but this is not the standard computer
notation.  ORACLE in the database stores number as character with up to 38 characters
in a decimal system, so there is no tranformation of the number.

Characters do not necessarily take more room for storage as 8 characters may
not use more space than a 64bit ieee number.  There should certainly be a descriptor
in the standard to identify the shape of a data block!
