Frequently asked questions
Yes. A fractional exponent like 0.5 takes a root (so 9^0.5 = 3), and a negative exponent gives a reciprocal (2^-3 = 0.125). The calculator uses JavaScript's Math.pow under the hood.
A negative base with a non-integer exponent gives a complex (imaginary) number, which this calculator does not display. Use an integer exponent for negative bases, or take the absolute value first.
The calculator returns 1, matching JavaScript's Math.pow convention. Mathematicians sometimes leave 0^0 undefined; this tool picks the common programming convention and notes it in the result.
