+ * Exponent sign handling is complex.

+ * comes out of the format if it is negative.
+ *
+ * In Excel, you always say whether to always show the sign ("e+") or only
+ * show negative signs ("e-").
+ *
+ * Also in Excel, where you put the sign in the format is NOT where it comes
+ * out in the result. In the format, the sign goes with the "e"; in the
+ * output it goes with the exponent value. That is, if you say "#e-|#" you
+ * get "1e|-5", not "1e-|5". This makes sense I suppose, but it complicates
+ * things.
+ *
+ * Finally, everything else in this formatting code assumes that the base of
+ * the result is the original format, and that starting from that situation,
+ * the indexes of the original special characters can be used to place the new
+ * characters. As just described, this is not true for the exponent's sign.
+ * <p/>
+ * So here is how we handle it:
+ *
+ * (1) When parsing the format, remove the sign from after the 'e' and put it
+ * before the first digit of the exponent (where it will be shown).
+ *
+ * (2) Determine the result's sign.
+ *
+ * (3) If it's missing, put the sign into the output to keep the result
+ * lined up with the output. (In the result, "after the 'e'" and "before the
+ * first digit" are the same because the result has no extra chars to be in
+ * the way.)
+ *
+ * (4) In the output, remove the sign if it should not be shown ("e-" was used
+ * and the sign is negative) or set it to the correct value.
