The workaround was to represent each list of doubles as two arrays: a
list of doubles and a list of ints. The list of doubles contained the
same contents as the original array except that NaN, Infinity, and
NegInfinity were replaced with 0. The second list contains flags that
described the values in the original array of doubles. The flags were:
0 for a real-valued double, 1 for NaN. 2 for Inf. 3 for NegInf. etc...
