Python abs() Function

Description

The abs() function returns the absolute value of x, that is, the positive distance between x and zero. The argument can be an integer, floating-point number, or complex number. If the argument is a complex number, its modulus is returned. The modulus of a complex number is the square root of the sum of the squares of its real and imaginary parts.

abs(x+ij)=sqrt{x^{2}+y^{2}}

Syntax

The syntax of the abs() function is as follows:

abs(x)

Parameters

• x − This is a numeric expression.

Return Value

This method returns the absolute value of x.

Example

The following example demonstrates how to use the abs() function.

x = -45
y = abs(x)
print ("x: ",x, "abs(x): ", y)

x = 100.12
y = abs(x)
print ("x: ",x, "abs(x): ", y)

x = 2+3j
y = abs(x)
print ("x: ",x, "abs(x): ", y)

When we run the above program, it produces the following results –

x: -45 abs(x): 45
x: 100.12 abs(x): 100.12
x: (2+3j) abs(x): 3.605551275463989
