It is the magnitude, or absolute value, of the real number.
A complex number has two components: a real component and an imaginary one, and is usually written in the form x+yi where i is the imaginary square root of -1. The real component of such a number is x.
The magnitude of a real number is its value without regard to its sign.
study it and its value
It is a real rational negative integer number whose value is -3
4.2 is a pure real (rational) number. It has no specific X value.
The absolute value of a number equals the number itself if and only if the number is a positive real number (x >= 0 and does not include a nonzero imaginary component).
