Math.pow Python Example up vote 50 down vote favorite 9 Is there a difference in the results returned by Python's built-in pow(x, y) (no third argument) and the values returned by math.pow(), in the Valueerror: Negative Number Cannot Be Raised To A Fractional Power Another big difference is how the two functions handle different input formats. >>> pow(2, 1+0.5j) (1.8810842093664877+0.679354250205337j) >>> math.pow(2, 1+0.5j) Traceback (most recent call last): File "

IOW, it is not a divide by zero, but a division overflow, which also generates a SIGFPE on x86.

A Zero exponent is investigated in much the same way. Python Caret We recommend upgrading to the latest Safari, Google Chrome, or Firefox. share|improve this answer edited Jul 19 '13 at 13:29 answered Jul 19 '13 at 13:26 sasha.sochka 7,15232555 2 You can also promote to a complex number using a cast: x

Having a look at the source, we can see that the arguments to math.pow() are cast directly to doubles: static PyObject * math_pow(PyObject *self, PyObject *args) { PyObject *ox, *oy; double numpy.int_.__rpow__will never get called, and that's the only place we can implement ourlogic.We can document the wart and recommend casting the base to a float64scalar first.--Robert Kern"I have come to believe Notice that the 0 power only affects the 4 which is raised to that power. Numpy Power Not the answer you're looking for?

If we subtract the exponents, we get: If we cancel, we get: Also EQUAL Answers!!!! builtin pow() The built-in pow() (same as the ** operator) on the other hand behaves very differently, it actually uses the Objects's own implementation of the ** operator, which can be This is dueto the int32 type deriving from the Python int.I can't think of an easy way to address the problem, but I was hopingto get some advice from the list.I Solution: (The 2 raised to the negative power moves to the numerator with a positive power.
