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.

Sintaxis:


    Val (Texto As String)

Valor de retorno:

Doble

Parámetros:

Texto: Cadena que representa un número.

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.

Códigos de error:

5 Llamada a procedimiento no válida

Ejemplo:


    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
        ' El ejemplo siguiente devuelve 0 (cero) dado que la cadena facilitada no comienza por un número
        MsgBox Val("A123.123") ' 0
    End Sub
