If you mean convert from a decimal base10 number to a base 16 number
then a search of this board or the web should get you an answer.
If it is an output issue take a look at the printf format options.
Inside the PIC numbers are in binary base 2 representation.
To try it yourself
Take the most significant nibble (4 bits) and convert it to an 8 bit binary representation of the character you want to see ( "1"..."9","A".."F". then the least significant nibble and convert it likewise.

If you want to convert a number DD to a string "0xDD", you can use sprintf(). Please treat the following code with some sarcasm, as I'm writing without the compiler or manual at hand; this is just to give you an idea:
Code:

int8 iNumber;
iNumber = 0xDD;
printf("0x%2X", iNumber);
