About This Calculator
This Cube Roots Calculator lets you calculate the real cube root (∛x) of any number, including negative values and decimals. It provides both a simplified result and a full decimal approximation up to 10 digits, along with a verification step by cubing the result.
How to Use
- Enter any real number (positive, negative, or zero) into the input field.
- Click the "Calculate" button to compute the cube root.
- View the result and the verification step (cube root raised to the power of 3).
Frequently Asked Questions
What is a cube root?
The cube root of a number is the value that, when raised to the power of 3, equals the original number. For example, ∛27 = 3, because 3³ = 27.
Can I enter negative numbers?
Yes. This calculator supports negative inputs and returns the corresponding negative cube root. For example, ∛-8 = -2.
Why doesn't the verification always exactly match the input?
Due to floating-point precision limitations in computers, cubing the result may yield a value very close to the input, but not always perfectly exact. This is normal and expected.
