Calculators are powerful tools that can perform various mathematical operations. If you’re looking to calculate the absolute value of a number using HTML and JavaScript, you’ve come to the right place. This article provides a step-by-step guide along with a working code snippet to help you achieve this task effortlessly.
Formula: The absolute value of a number is its distance from zero on the number line, irrespective of its direction. In mathematical terms, if ‘x’ is a real number, then the absolute value of ‘x’ is denoted as |x| and is defined as follows:
- |x| = x, if x is greater than or equal to 0
- |x| = -x, if x is less than 0
How to Use:
- Enter a numeric value into the provided input field.
- Click the “Calculate” button.
- The absolute value of the entered number will be displayed.
Example: Let’s say you want to find the absolute value of -5. Enter -5 in the input field, click “Calculate,” and the result will be 5.
