Done.

	extras/complex_numbers/complex_float.m:
	extras/complex_numbers/float_complex.m:
		Fix some compile errors.

`cartesian_to_polar' and `polar_to_cartesian' do not exist.
complex_float.m and float_complex.m were not included
in the complex_numbers library before my change, so they
weren't ever being compiled.
