DecimalFormat is for formatting decimal numbers with usage of a patterns. Symbol Meaning 0 a digit # a digit, zero shows as absent . placeholder for decimal separator , placeholder for grouping separator. E separates mantissa and exponent for exponential formats. ; separates formats. - default negative prefix. % multiply by 100 and show as percentage ‰ multiply by 1000 and show as per mille ¤ currency sign; replaced by currency symbol; if doubled, replaced by international currency symbol. If present in a pattern, the monetary decimal separator is used instead of the decimal separator. X any other characters can be used in the prefix or suffix ' used to quote special characters in a prefix or suffix. Notes If there is no explicit negative subpattern, - is prefixed to the positive form. That is, "0.00" alone is equivalent to "0.00;-0.00". If there is an explicit negative subpattern, it serves only to specify the negative prefix and suffix; the number of digits, minimal digits, and other characteristics are all the same as the positive pattern. That means that "#,##0.0#;(#)" has precisely the same result as "#,##0.0#;(#,##0.0#)". The exponent character must be immediately followed by one or more digit characters. Example: "0.###E0". The number of digit characters after the exponent character gives the minimum exponent digit count; there is no maximum. Negative exponents are denoted using the same prefix and/or suffix specified for the number itself. The minimum number of integer digits is achieved by adjusting the exponent. The maximum number of integer digits, if any, specifies the exponent grouping. For example, 12345 is formatted using "##0.###E0" as "12.345E3". Illegal patterns, such as "#.#.#" or mixing '_' and '*' in the same pattern, will cause an IllegalArgumentException to be thrown. From the message of IllegalArgumentException, you can find the place in the string where the error occurred. The grouping separator is commonly used for thousands, but in some countries for ten-thousands. The interval is a constant number of digits between the grouping characters, such as 100,000,000 or 1,0000,0000. If you supply a pattern with multiple grouping characters, the interval between the last one and the end of the integer is the one that is used. So "#,##,###,####" == "######,####" == "##,####,####".
