The Zero Power Rule states that any non-zero number raised to the power of zero equals 1. Therefore, we have:
\[ (-1.478)^0 = 1 \]
Now we can substitute this back into the expression:
\[ 2.3 + (-1.478)^0 = 2.3 + 1 \]
Calculating this gives:
\[ 2.3 + 1 = 3.3 \]
Thus, the final result is:
\[ \boxed{3.3} \]
