How to convert binary or hexa to decimal?

[Adam]

Hello,

I'm trying to decifer the data in the table that stores the data in the
binary format. All numbers are placed in binary fields.

For example the content of the field is:
(0xB4F5000000000000) in unicode and defined as binary(8).

Are there any procedures that convert the unicode binary (or hexa) numbers
back to ascii or readable form?

Any help is appreciated,
Adam
