MySQL ABS() Function

The ABS() function in MySQL calculates the absolute value of a number. The absolute value of a number is its distance from zero, always resulting in a non-negative value.



ABS(): Definition and Usage

ABS() is a simple but useful mathematical function. It's frequently used to remove the sign (positive or negative) from a number, ensuring that you are working with only the magnitude of the value. This is commonly needed in calculations or comparisons where the sign is not relevant.
