Anyone know Intel assembly, I need help

[Vectorferret]

So, what I have to do is take an arbitrary 2 byte signed integer (standard C int really) and determine it's decimal ASCII. That is, if I had $FFFFFFFF I'd need to to create the string "-1" or $0000000F and create the string "16". Needs to be Intel assembly (not exactly a challenge in a high level language). Does anyone know how to manage it? Thanks
