Double.parseDouble and FastDoubleParser.parseDouble return different results for the string "0e555":

Double.parseDouble("0e555"): 0.0
FastDoubleParser.parseDouble("0e555"): Infinity

Edit: I believe that is caused by the special case at

FastDoubleParser/src/ch/randelshofer/math/FastDoubleParser.java

Line 1089 in daa2392

return negative ? Double.NEGATIVE_INFINITY : Double.POSITIVE_INFINITY;
, which does not handle the even more special case of the mantissa being 0.
