What does the exponent calculator compute?

It computes base^exponent using the standard power function. A fractional exponent gives a root (base^0.5 is the square root), and a negative exponent gives the reciprocal (base^-1 = 1/base).

How accurate is the calculation?

It uses IEEE-754 double-precision floating point rounded to ten decimals for display. This is exact for integer powers within range; a negative base with a non-integer exponent is mathematically complex and is reported as undefined.

Is my input sent anywhere?

No. The calculator is privacy-first — the base and exponent stay in your browser and nothing is transmitted to any server.

Exponent Calculator (Power Calculator)

Raise any base to any power — including negative and fractional exponents.

Exponent (power) calculator

Raise any base to any exponent. The tool supports whole, negative and fractional powers — so base^0.5 gives a square root and base^-1 gives the reciprocal. Very large results are shown in scientific notation.

It is privacy-first: every calculation runs locally in your browser, so the numbers you enter never leave your device.
