Decimal points To format fractions or numbers with decimal points, include the following digit placeholders in a section. If the number has more digits to the right of the decimal point than there are placeholders in the format, the number is rounded to as many decimal places as there are placeholders. If the number has more digits to the left of the decimal point than there are placeholders in the format, the extra digits are displayed. If the format contains only number signs (#'s) to the left of the decimal point, numbers less than 1 begin with a decimal point.
The placeholder # displays only significant digits; it does not display insignificant zeros.
To display 
Use this format code 
1234.59 as 1234.6 
####.# 
The placeholder 0 (zero) displays insignificant zeros if a number has fewer digits than there are 0's in the format.

12 as 12.0, and 1234.568 as 1234.57 
#.0# 
The placeholder ? adds spaces for insignificant zeros on either side of the decimal point so that when formatted with a fixedwidth font, such as Courier New, decimal points align. You can also use this symbol for fractions that have varying numbers of digits.
