I'll assume you meant to reply to everyone, but only replied to me.

I showed you how in my previous reply with sprintf. You can use either
the dec2hex or sprintf functions to convert a number into a *string*
displaying the hexadecimal representation.
>> sprintf ("0x%04X", bitand (0x55AA, 0xF0F0))
ans = 0x50A0
>> dec2hex (bitand (0x55AA, 0xF0F0))
ans = 50A0
You could also use `format hex` and ensure that all of your variables
are integer types.
>> format hex
>> a = uint16 (0x55aa)
a = 55aa
>> b = uint16 (0xf0f0)
b = f0f0
>> bitand (a, b)
ans = 50a0
I'm not sure what you mean by “output as a hex value…when you do a range
