Yes. A negative exponent gives the reciprocal, for example 2 to the power of -2 = 0.25, and a fractional exponent works like a root, for example 9 to the power of 0.5 = 3.
Extremely large results are shown as "Infinity" or "-Infinity". Combinations that have no real answer, such as a negative base raised to a fractional exponent, show "Result is not a real number" instead of a value.
