Returns the numbers contained in a string as a numeric value of appropriate type.
The Val function stops reading the string at the first character that it can't recognize as part of a number. Symbols and characters that are often considered parts of numeric values, such as dollar signs and commas, are not recognized.
However, the function recognizes the radix prefixes
&O (for octal) and
&H (for hexadecimal). Blanks, tabs, and linefeed characters are stripped from the argument.
The following returns the value 1615198:
Val(" 1615 198th Street N.E.")
In the following code, Val returns the decimal value -1 for the hexadecimal value shown:
The Val function recognizes only the period ( . ) as a valid decimal separator. When different decimal separators are used, as in international applications, use CDbl instead to convert a string to a number.
This example uses the Val function to return the numbers contained in a string.
Dim MyValue MyValue = Val("2457") ' Returns 2457. MyValue = Val(" 2 45 7") ' Returns 2457. MyValue = Val("24 and 57") ' Returns 24.
