Examples of java.text.DecimalFormat.format()

java.text.DecimalFormat.format()
Formats a number and appends the resulting text to the given string buffer. The number can be of any subclass of {@link java.lang.Number}.
This implementation uses the maximum precision permitted. @param number the number to format @param toAppendTo the StringBuffer to which the formattedtext is to be appended @param pos On input: an alignment field, if desired.On output: the offsets of the alignment field. @return the value passed in as toAppendTo @exception IllegalArgumentException if number isnull or not an instance of Number. @exception NullPointerException if toAppendTo or pos is null @exception ArithmeticException if rounding is needed with roundingmode being set to RoundingMode.UNNECESSARY @see java.text.FieldPosition
