Phase of a complex number is wrongly understood to be zero by MATLAB

I am doing a calculation of the phase of a complex number. However, the magnitude of this number is so small (around the order of 10^-400) so that MATLAB assumes both its magnitude and phase to be zero. So, I guess one way to get the correct phase is to decrease MATLAB's smallest number. But I doubt that's impossible. Any trick to get around this?

The smallest number that MATLAB can represent numerically is about 4.94065645841247e-324 . 10^(-400) is right out for numeric work.
For higher precision you need to go for the Symbolic Toolbox.
