Setting aside, for the moment, why you want to include studio.h...
Decimal is a property of a display device such as printing to a screen.
All(most all) values are stored in computers in binary representation.
Since there is no way to "print" anything directly from a mote, we are
somewhat confused as to where you want to get a "decimal equivalent"?
If you have a PC-host program that is receiving data from a mote you
can use something like this
in Java:
System.out.println( "my data = " + myIntValue );
or in C:
printf( "my data = %d", myIntValue );
Both of which convert a binary value to a string of characters in decimal
format on your screen. The second example legally requires that you
#include <studio.h>
to get the prototype for printf(), so maybe that is why you ask about that.
However neither of the above will do much good in a TOS program, aside
perhaps from a simulation, because there is no screen to print to.
Continuing on and reading into your posted code example...taking the
ones-compliment of something named Msg->strength leads me to believe that
you are trying to get an RSSI value in dbm. If that is the case then you
are partially implementing instructions for a well trodden path. Please
search this list, documentation, and manuals for RSSI and signal strength
to see the right way to do it.
