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.
The abs() Function takes a single number as a parameter. Number can either a float, integer or complex number.
abs() function removes any negative sign that may be present on a negative integer.
result = abs(5) result = abs(-55)
#OUTPUT 5 55
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
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
This marks the end of the Python abs Function. Any suggestions or contributions for CodersLegacy are more than welcome. Questions can be asked in the comment section below.
