# Abs() Function In Python

## Mathematical Background:

For any real number x, the absolute value is the magnitude of the number without the associated sign part.

abs(param)

## Method Overview:

The abs() function returns the absolute value of the parameter.

## Parameters:

param - Parameter can be an integer, a floating point value or a complex number.

## Note:

When the parameter is a complex number its magnitude is returned.

## Python Example Program using abs() function:

 #find absolute value of a negative integer NegativeInt = -7 absValue    = abs(-NegativeInt) print("Absolute value of given negtive integer {} is {}".format(NegativeInt, absValue))   #find absolute value of a negative floating point number NegativeReal = -7.5 absValue    = abs(-NegativeReal) print("Absolute value of given negative real number {} is {}".format(NegativeReal, absValue))   #find absolute value of a complex number complexNum = complex(-7.0,2.0) absValue    = abs(-complexNum) print("Absolute value of given complex number {} is {}".format(complexNum, absValue))

## Output of Python Example Program that uses the abs() function:

 Absolute value of given negative integer -7 is 7 Absolute value of given negative real number -7.5 is 7.5 Absolute value of given complex number (-7+2j) is 7.280109889280518
