Absolute Value Calculator

Concepts

Absolute value is the distance of a number from zero on a number line. It is a measure of the magnitude of a number, without regard to its sign. The absolute value of a number can be positive, negative, or zero.

Formula

The absolute value of a number is denoted by the vertical bars | on either side of the number. The absolute value of a number can be calculated using the following formula:

|x| = x if x >= 0
|x| = -x if x < 0

where x is any number.

For example, the absolute value of 5 is 5, because 5 is greater than or equal to 0. The absolute value of -5 is also 5, because -5 is less than 0.

Benefits

There are a number of benefits to using an absolute value calculator:

• Accuracy: Absolute value calculators are very accurate. They can calculate the absolute value of a number with a high degree of precision.
• Convenience: Absolute value calculators are very convenient to use. They are available online and can be used from anywhere with an internet connection.
• Speed: Absolute value calculators can perform calculations very quickly. This can be helpful for students, engineers, and other professionals who need to calculate the absolute value of numbers on a regular basis.

Interesting facts
