VAL returns the numeric value of a string of digits.
 
VAL(stringexpression$)
    ■ The argument stringexpression$ is a sequence of characters that
      can be interpreted as a numeric value.
 
Usage Notes
    ■ The VAL function stops reading the string at the first character that
      it cannot recognize as part of a number. The VAL function also strips
      blanks, tabs, and line feeds from the argument string. For example,
      the code below returns the value 1615198
 
        VAL("    1615 198th Street")
