python Programming Glossary: math.powDifference between the built-in pow() and math.pow() for floats, in Python? http://stackoverflow.com/questions/10282674/difference-between-the-built-in-pow-and-math-pow-for-floats-in-python between the built in pow and math.pow for floats in Python Is there a difference in the results returned.. in pow x y no third argument and the values returned by math.pow in the case of two float arguments. I am asking this question.. I am asking this question because the documentation for math.pow implies that pow x y i.e. x y is essentially the same as math.pow..
