Do I need a SWIG typemap to have a c function return a float to python?

I'm trying to call a C function from python. This function takes a number of arrays as input and returns a float.

Do I need a SWIG typemap to do this? One concern is that python doesn't make a distinction between floats, double, etc and I'm specifically interested in returning only c-type float.

Returning float "just works". You don't need additional typemaps:

test.i

%module test

%inline %{
    float func(void) { return 1.5; }
%}

After running swig and compiling the result:

>>> import test
>>> test.func()
1.5
