The Zero Power Rule of Integer Exponents states that any non-zero number raised to the power of 0 is equal to 1.
In this case, we have:
\[ (-1.478)^0 = 1 \]
Now we can substitute this back into the original expression:
\[ 2.3 + (-1.478)^0 = 2.3 + 1 \]
Adding these together gives us:
\[ 2.3 + 1 = 3.3 \]
Therefore, the final answer is:
\[ \boxed{3.3} \]
