03 / Website use cases
Where to use square root calculator
Maths lessons, homework help and trade pages often need square roots, and a plain calculator only gives a long decimal. Square root calculator sits on your own page: visitors type a number and see the exact simplified form for whole numbers, such as √72 = 6√2, a decimal rounded to the places you choose, the working and the nearest square numbers, all updated as they type. Nothing is sent anywhere.

Find the side of a square area in metres or feet.
Homework help pages
Give readers a quick check next to your explanation.

Troubleshoot square root calculator
Check these settings if the published page behaves differently from the editor.
Why do negative numbers show a message?
They have no real square root. Turn on Allow negative numbers to show an imaginary root such as 3i.
Why is there no exact form for 2.5?
Exact forms are shown for whole numbers. Decimals get an exact answer only when the root ends, such as √2.25 = 1.5.
Why does “1,000” give 1?
A comma is read as a decimal point. Type numbers without thousands separators.
How large can the number be?
Up to 15 digits before the decimal point and 10 after it.
