How can I print 64-bit hex numbers using the SPRINTF function?

I would like to print large 64-bit hex numbers using the SPRINTF function

Executing the SPRINTF function results in the following:

sprintf('%x', 4294967296)

ans =

         4.294967e+009

sprintf('%x', 4294967295)

 ans =

       ffffffff

This enhancement has been incorporated in Release 2010b (R2010b). For previous product releases, read below for any possible workarounds:

The abillity to print 64-bit hex numbers using the SPRINTF function is not available in MATLAB.

To work around this issue, use the following command to print the numbers in hex format:

sprintf('%c', dec2hex(4294967296))

1. This would help you to print out the numbers which are greater than 2^32 in hex format.

2. However, you can only use the range from 0 to 2^52 as the DEC2HEX function gives unpredictable results for nonnegative numbers greater than 2^52. You will get the warning regarding the same in this case.
