I get a negative zero when printing a set of coefficients of lasso regression:

>> format longg
>> fprintf('%e\n',B(:,86))


I can't provide simple code to do duplicate. A simply cut/paste of the above text to assign into a variable x does not yield the same fprintf results.

What would cause the negative zero? How should it be interpretted?
