Input	Format	Output
123456.789	###,###.###	123,456.789	The pound sign (#) denotes a digit, the comma is a placeholder for the grouping separator, and the period is a placeholder for the decimal separator.
123456.789	###.##	23456.79	The value has three digits to the right of the decimal point, but the pattern has only two. The format method handles this by rounding up.
123.78	000000.000	00123.780	The pattern specifies leading and trailing zeros, because the 0 character is used instead of the pound sign (#).
12345.67	$###,###.###	$12,345.67	The first character in the pattern is the dollar sign ($). Note that it immediately precedes the left most digit in the formatted output.

y	Year	yy or yyyy gives 96 or 1996
M	Month	MM will give a 2 digit month, more than 2 M's will give a text name (MMM = Jul) Note:mm is minutes
w *	Week in year	ww would return a number from 01-53
W *	Week in Month	W would return a number from 1-5
D *	Day in year	DDD would give the day of the year (001-366)
d *	Day in month	dd would give the day of the month (01-31)
F	Day of week in month	F would give a number from 1-7
