fprintf output: What does 0 mean?
Posted:

I get a negative zero when printing a set of coefficients of lasso regression:
>> format longg >> fprintf('%e\n',B(:,86)) 0.000000e+00 0.000000e+00 0.000000e+00 1.367172e01 0.000000e+00 6.460915e02 1.078923e10
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?
