doubles in embedded python

Question

So I'm writing a set of C++ classes that run Python scripts. I've gotten code working to run any script I want from a specified directory, and I can pass and return values just fine.

But the one issue I have is I can't seem to find out how to set Python doubles up. For example, when I was using long values, I could use "PyLong_AsLong([whatever value I'm trying to convert to a long from a PyObject])" -- but is there a PyDouble_Something in the Python/C API I can use for that? My google searching has so far turned up nothing.

You want PyFloat_AsDouble, no?

Yeah, I just found out about the PyFloat objects and Python using floats as doubles. Thank you :) – Mister R2 Jul 12 '12 at 02:38

I found out the answer. I was mistaken, and I thought there were doubles in Python, but there aren't. I got it to work using a "PyFloat" object, and just converted the double like this:

"PyFloat_FromDouble([the double I wanted as a PyObject])"
