how to change interpretation int - hex

tbrake

Hallo How can i change the interpretation of a variable. Example int text = 123456; // editable by user !! ... // On one position I need to convert to 0x123456 ... THX Timen

_anil_

This should work!!!

  int nText = 12345;
  char  szText[10];
  int nHex =0;
  itoa(12345, szText, 10);
  nHex = strtol( szText, NULL, 16);

Either write your own converter (multiply each digit with powers of 16), or convert to string using sprintf and convert back to hex using sscanf. Cheers Steen.

This makes non-sense. A number is neither in decimal, in hexa, or whatever else; it is just a number. Its representation may change but the number will always be the same. You can say 0x14 or 20 or 0b10100, all these three strings represent the same number. -- modified at 7:23 Friday 2nd June, 2006 Sorry, I misread the thread :)

Hallo 1. Well at least it makes sence. cause i have to controll some hardware. To calculate the needed commands the shortes way is to interprete int as Hex bit shift this and the result is the needed command. Outherwice if you cant see the sence then become a lectural 2. int - char - hex is what i have and this is as fast doing a lot of if else combinations - well but i need somthing fast - much faster ?!?! Well the THX Timen:->

123456 in base-16 is 0x1E240. Use itoa() or sscanf() to do the conversion.

cout<<hex<<123233;//displays in hexadecimal format.
cout<<oct<<121223;//displays in octal format.
cout<<dec<<12323;//displays in decimal format.
