# Val Function

Use the Val function to convert a string that represents a number into numeric data type.

The string passed to the Val function is locale-independent. This means that commas are interpreted as thousands separators and a dot is used as the decimal separator.

### Syntax:

        Val (Text As String)

### Return value:

Double

### Parameters:

Text：表示數字的字串。

If only part of the string contains numbers, only the first appropriate characters of the string are converted. If the string does not contain any numbers then Val returns 0.

### Example:

        Sub ExampleVal
            MsgBox Val("123.1") + 1 ' 124.1
            ' Below 123,1 is interpreted as 1231 since "," is the thousands separator
            MsgBox Val("123,1") + 1 ' 1232
            ' All numbers are considered until a non-numeric character is reached
            MsgBox Val("123.4A") ' 123.4
            ' The example below returns 0 (zero) since the string provided does not start with a number
            MsgBox Val("A123.123") ' 0
        End Sub
