Difference between ToString(“N2”) and ToString(“0.00”)

From Standard Numeric Format Strings

The number is converted to a string of
the form “-d,ddd,ddd.ddd…”, where ‘-‘
indicates a negative number symbol if
required, ‘d’ indicates a digit (0-9),
‘,’ indicates a thousand separator
between number groups, and ‘.’
indicates a decimal point symbol.

It would seem that N will include thousands separators, whereas 0.00 will not.
