Frequently asked questions
A perfect square is a non-negative integer whose square root is also an integer — for example, 144 (12 × 12) or 10000 (100 × 100). The calculator labels the result "Yes" or "No" for this check.
The square root of a negative number is imaginary (involves the imaginary unit i), which this calculator does not display. Take the absolute value first, or use a calculator that supports complex numbers.
It uses JavaScript's Math.sqrt, which is IEEE-754 double precision — accurate to about 15 significant digits. The display rounds to 8 decimal places.
