“.” • A decimal point is inserted. A decimal point can be
inserted at any place in the format.
• If a format string is placed following a decimal point,
the corresponding digits are always displayed.
• 0 is displayed for redundant digits in the decimal
part.
• If the number of decimal places in the format string
is smaller than the number of digits in the decimal
part of a numeric value, the numeric value is
rounded to the specified digit and displayed.
• If the number of digits of a numeric value exceeds
the number of digits in the format as a result of
rounding up the numeric value, % is displayed
before the rounded numeric value.
