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