Re: Conversion to Hexadecimal

[Rod Nussbaumer <bomr@triumf.ca>]

Ishita:

You are confusing the *human-readable representation* of numeric data 
with the actual value of the stored data. The method to convert to any 
particular radix *for display* depends on the code or tool that you use 
to print or display it. Perhaps if you tell us something about that, 
someone can suggest an appropriate method.
If you are writing C code to display the data, for instance, you can 
simply use one of the printf() family functions with the appropriate 
format specifiers. In your case, wanting to display the data in 
hexadecimal notation, you would likely use the '%X' specifier, or 
perhaps modify it to provide more consistent formating: '%02X', for example.
