Rif.: decimal to hexadecimal

[chayma]

How can i convert an integer to hexadecimal string in CVI ?

CVI 2017

thanks

Using "%x" format code in sprintf. This is not CVI, it's pure C

j'ai  utilisé  Fmt (hex, "%x<%i",dec) mais ça ne marche pas

[RobertoBozzolo · Accepted solution]

Since in this case Fmt expects an integer in output, the correct format should be

Fmt (&hex, "%x<%i", dec);

But this is really useless: there will be no difference in memory between dec and hex! As you surely know, hexadecimal, decimal, octal, binary... are only representations of the very same thing.

You correctly stated in your original question that you wanted a "hexadecimal string", so the correct call should be

char	string[16];

Fmt (string, "%s<0x%x", dec);

Merci pour la réponse

Ça marche bien 

Est-ce vous pouvez m'indiquer l'instruction qui convertir de hexadécimal au décimal 

Et merci d'avance

That is, extract the number from an hexadecimal string?

sscanf (string, "%x", &dec);
