Returning a Hex value from an integer

Question asked by David Nguyen on Mar 6, 2009

I am using the 16 bit 9S12C128 MCU.  I wrote this simple code to return a hex value from an integer input.

 

 

word dec_to_hex(signed short number)
{
  word hex_value;
  hex_value = number;

 

  return hex_value;  
}

 

 

What I would like to know is, does this return a 16 bit hex value (i.e. input = 32767, returns 0x7FFF; input = -32768, returns 0x8000)?  I can't really check the output because when I use "%d", I get an integer value; and when I use a "%x", I get the hex value.

 

The reason for this is so that I can output the hex value to a DAC.  Also, the data type "word" in a 16 bit MCU means that one word is 16 bits and the data type "dword" means 32 bits?

 

I have googled this but I could never get a clear answer.  Any help is appreciated.  Thanks in advance.
