[Mono-list] IntegerFormatter

[Derek Holden]

Hey Nick,

I think the error may be in the SByte test. Format type "n" is listed in the
EMCA IFormattable doc as:

n  Number Format: Used for strings in the following form:

[-]d,ddd,ddd.dd...d

The minus sign ("-") appears only if the number is negative. At least one
non-zero digit (d) precedes the decimal separator ("."). The precision
specifier determines the number of decimal places (dd.d). If the precision
specifier is omitted, NumberFormatInfo.NumberDecimalDigits determines the
number of decimal places in the string. Results are rounded to the nearest
representable value when necessary. The NumberGroupSizes,
NumberGroupSeparator, and NumberDecimalSeparator members of a
NumberFormatInfo supply the size and separator for digit groupings, and
decimal separator, respectively.

I know in currency format and percent format that parenthesis are used for
negative values, but that is determined by
NumberFormatInfo.CurrencyNegativePattern and
NumberFormatInfo.PercentNegativePattern, which are defined in the
NumberFormatInfo spec.
