I am trying to store a negative number, and then on a function call, read it. But I only get the positive Felt number.

Felts are module P (a big prime) so -1 == P - 1 that's why you only see positive numbers. If you wish to do mathematical operations that take into account the sign of the felt you can use the functions prefixed with sign here.
