Parameters

string

Specify a string expression which contains only numeric characters. The string may also contain a prefix:
&H (hexadecimal), &O (octal), or &B (binary).

Return Values
Returns an integer or floating point result depending upon the input string. If the input string has a decimal point character than the number is converted into a floating point number. Otherwise the return value is an integer.

Val Function Example
The example shown below shows a program which coverts several different strings to numbers and then prints them to the screen.

Function ValDemo
    String realstr$, intstr$
    Real realsqr, realvar
    Integer intsqr, intvar

    realstr$ = "2.5"
    realvar = Val(realstr$)
    realsqr = realvar * realvar
    Print "The value of ", realstr$, " squared is: ", realsqr

    intstr$ = "25"
    intvar = Val(intstr$)
    intsqr = intvar * intvar
    Print "The value of ", intstr$, " squared is: ", intsqr
Fend

Here's another example from Command window.
