# Number

### General

Numeric values are represented by multiple data types in Visual Basic .NET:

-  [Byte Data-Type](https://learn.microsoft.com/en-us/dotnet/visual-basic/language-reference/data-types/byte-data-type)
-  [Decimal Data-Type](https://learn.microsoft.com/en-us/dotnet/visual-basic/language-reference/data-types/decimal-data-type)
-  [Double Data-Type](https://learn.microsoft.com/en-us/dotnet/visual-basic/language-reference/data-types/double-data-type)
-  [Integer Data-Type](https://learn.microsoft.com/en-us/dotnet/visual-basic/language-reference/data-types/integer-data-type)
-  [Long Data-Type](https://learn.microsoft.com/en-us/dotnet/visual-basic/language-reference/data-types/long-data-type)
-  [Single Data-Type](https://learn.microsoft.com/en-us/dotnet/visual-basic/language-reference/data-types/single-data-type)

However, these data types are very similiar, so for the usage within Mail & Deploy it's sufficient to treat them all the same in most cases.

### Constants

You can specify constant numeric values in Mail & Deploy using a dot as the decimal separator; group separators cannot be provided when specifying constant numeric values. The following expression returns the number 12:

          Mail & Deploy Expression

          

12

The following expression returns the number 1.512,75 (one thousand five-hundred and twelve decimal seventy-five):

          Mail & Deploy Expression

          

1512.75

### Operators

Numeric values support the following operators:

| Operator | Description |
| --- | --- |
| + | This operator adds two numeric values. |
| - | This operator subtracts the numeric value to the right of the minus sign from the numeric value to the left of the minus sign. |
| * | This operator multiplies both numeric values. |
| / | This operator divides the number left of the division sign through the number right of the division sign. |

### Formatting

A numeric number can be formatted by using the [Format](/release34/docs/format) function and supplying the number to format as well as the [Format String](/release34/docs/format-strings) to apply. The following example formats the number *1234* with a resulting string that contains group and decimal separators and two decimal digits:

          Mail & Deploy Expression

          

Format(1234, "#,##0.00")
