Thus, to scale a number by 1 million and insert group separators, use a custom format similar to " , 0,,". If the custom format does not contain a decimal separator, the number is rounded to the nearest integer. If the number has more digits than there are Zero or Digit placeholders to the left of the decimal separator, the extra digits are copied to the output string immediately before the first Zero or Digit placeholder. A custom format can contain up to three sections separated by section separator characters, to specify different formatting for positive, negative, and zero values.
The sections are interpreted as follows:. One section : The custom format applies to all values positive, negative and zero. Negative values include a negative sign. Two sections : The first section applies to positive values and zeros, and the second section applies to negative values. If the value to be formatted is negative, but becomes zero after rounding according to the format in the second section, then the resulting zero is formatted according to the first section. Negative values do not include a negative sign to allow full control over representations of negative values.
For example, a negative can be represented in parenthesis using a custom format similar to ". Three sections : The first section applies to positive values, the second section applies to negative values, and the third section applies to zeros. The second section can be empty nothing appears between the semicolons , in which case the first section applies to all nonzero values, and negative values include a negative sign.
If the number to be formatted is nonzero, but becomes zero after rounding according to the format in the first or second section, then the resulting zero is formatted according to the third section. Enum and System. DateTime types also support using format specifiers to format string representations of values. See System. DateTimeFormatInfo for a comprehensive list of the format specifiers supported by each type.

Scientific Engineering Format: Used for strings in one of the following forms: [-] m. Fixed-Point Format: Used for strings in the following form: "[-] m. The default precisions for integral types are as follows: System. UInt16 : 5 System. UInt32 : 10 System. If the precision specifier is omitted, the following default precisions are used: System.
Single : 7 System. Double : 15 System. Decimal : 29 For all types: The number of digits that appear in the result not including the exponent will not exceed the value of the precision specifier; values are rounded as necessary. The decimal point and any trailing zeros after the decimal point are removed whenever possible.
Number Format: Used for strings in the following form: [-] d,ddd,ddd. The result is scaled by Round trip Format: This format is valid only when specified with System. Double or System. Used to ensure that the precision of the string representation of a floating-point value is such that parsing the string does not result in a loss of precision when compared to the original value.
If the maximum precision of the data type 7 for System. Single , and 15 for System. Double would result in a loss of precision, the precision is increased by two decimal places.
If a precision specifier is supplied with this format specifier, it is ignored. This format is otherwise identical to the fixed-point format. Hexadecimal Format: This format is valid only when specified with integral data types.
Used for string representations of numbers in Base The precision determines the minimum number of digits in the string. If the precision specifies more digits than the number contains, the number is left-padded with zeros. NumberDecimalSeparator property determines the symbol used as the decimal separator.
