Description

Examples

"0"

Zero placeholder

Replaces the zero with the corresponding digit if one is present; otherwise, zero appears in the result string.

1234.5678 ("00000") -> 01235

0.45678 ("0.00", en-US) -> 0.46

0.45678 ("0.00", fr-FR) -> 0,46

"#"

Digit placeholder

Replaces the "#" symbol with the corresponding digit if one is present; otherwise, no digit appears in the result string.

Note that no digit appears in the result string if the corresponding digit in the input string is a non-significant 0. For example, 0003 ("####") -> 3.

1234.5678 ("#####") -> 1235

0.45678 ("#.##", en-US) -> .46

0.45678 ("#.##", fr-FR) -> ,46

"."

Decimal point

Determines the location of the decimal separator in the result string.

0.45678 ("0.00", en-US) -> 0.46

0.45678 ("0.00", fr-FR) -> 0,46

","

Group separator and number scaling

Serves as both a group separator and a number scaling specifier. As a group separator, it inserts a localized group separator character between each group. As a number scaling specifier, it divides a number by 1000 for each comma specified.

Group separator specifier:

2147483647 ("##,#", en-US) -> 2,147,483,647

2147483647 ("##,#", es-ES) -> 2.147.483.647

Scaling specifier:

2147483647 ("#,#,,", en-US) -> 2,147

2147483647 ("#,#,,", es-ES) -> 2.147

"%"

Percentage placeholder

Multiplies a number by 100 and inserts a localized percentage symbol in the result string.

0.3697 ("%#0.00", en-US) -> %36.97

0.3697 ("%#0.00", el-GR) -> %36,97

0.3697 ("##.0 %", en-US) -> 37.0 %

0.3697 ("##.0 %", el-GR) -> 37,0 %

"‰"

Per mille placeholder

Multiplies a number by 1000 and inserts a localized per mille symbol in the result string.

0.03697 ("#0.00‰", en-US) -> 36.97‰

0.03697 ("#0.00‰", ru-RU) -> 36,97‰

"E0"

"E+0"

"E-0"

"e0"

"e+0"

"e-0"

Exponential notation

If followed by at least one 0 (zero), formats the result using exponential notation. The case of "E" or "e" indicates the case of the exponent symbol in the result string. The number of zeros following the "E" or "e" character determines the minimum number of digits in the exponent. A plus sign (+) indicates that a sign character always precedes the exponent. A minus sign (-) indicates that a sign character precedes only negative exponents.

987654 ("#0.0e0") -> 98.8e4

1503.92311 ("0.0##e+00") -> 1.504e+03

1.8901385E-16 ("0.0e+00") -> 1.9e-16

"\"

Escape character

Causes the next character to be interpreted as a literal rather than as a custom format specifier.

987654 ("\###00\#") -> #987654#

'string'

"string"

Literal string delimiter

Indicates that the enclosed characters should be copied to the result string unchanged.

68 ("# 'degrees'") -> 68 degrees

68 ("#' degrees'") -> 68 degrees

;

Section separator

Defines sections with separate format strings for positive, negative, and zero numbers.

12.345 ("#0.0#;(#0.0#);-\0-") -> 12.35

0 ("#0.0#;(#0.0#);-\0-") -> -0-

-12.345 ("#0.0#;(#0.0#);-\0-") -> (12.35)

12.345 ("#0.0#;(#0.0#)") -> 12.35

0 ("#0.0#;(#0.0#)") -> 0.0

-12.345 ("#0.0#;(#0.0#)") -> (12.35)

Other

All other characters

The character is copied to the result string unchanged.

68 ("# °") -> 68 °
