Python math.fabs() function
The math.fabs()
function in Python is used to return the absolute value of a number as a float. Unlike the built-in abs()
function, which can return an integer or a float depending on the input, math.fabs()
always returns a float.

Summary
- The
math.fabs()
function calculates the absolute value of a number, ensuring the result is returned as a float. - It is useful when you specifically want a float output, regardless of whether the input is an integer or a float.
