Examples of java.text.NumberFormat.format()

java.text.NumberFormat.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 extracts the number's value using {@link java.lang.Number#longValue()} for all integral type values thatcan be converted to long without loss of information, including BigInteger values with a {@link java.math.BigInteger#bitLength() bit length} of less than 64,and {@link java.lang.Number#doubleValue()} for all other types. Itthen calls {@link #format(long,java.lang.StringBuffer,java.text.FieldPosition)}or {@link #format(double,java.lang.StringBuffer,java.text.FieldPosition)}. This may result in loss of magnitude information and precision for BigInteger and BigDecimal values. @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 orpos is null @exception ArithmeticException if rounding is needed with roundingmode being set to RoundingMode.UNNECESSARY @see java.text.FieldPosition
