This article covers the use of the Python abs Function.
The Python abs Function is an built-in function that returns the absolute value for a given number. In the case of a complex number, the absolute value is the magnitude of it’s real and imaginary parts.
Syntax
The abs() Function takes a single number as a parameter. Number can either a float, integer or complex number.
abs(number)
Integer
The abs()
function removes any negative sign that may be present on a negative integer.
result = abs(5)
result = abs(-55)
#OUTPUT
5
55
Float
The abs()
function removes any negative sign that may be present on a negative float number.
result = abs(5.4)
result = abs(-5.67)
#OUTPUT
5.4
5.67
Complex Number
The abs()
function calculates the magnitude using the formula magnitude = (Re^2 + Im^2)^1/2
. For this reason, negative signs do not have any effect on the output. Any negative sign is removed when the real and imaginary parts are squared.
result = abs(3 + 4i)
result = abs(-3 - 4i)
#OUTPUT
5
5
