<B>VAL Numeric Value of a String</B>
|

<B>Notes:</B> VAL attempts to extract a number from the first characters
|
||
|
|
of its argument. In doing so, it ignores leading blanks,
|
||
|
|
tabs, and line feeds, and treats a single hyphen as
|
||
|
|
signifying negation. For example, VAL(" -32 Main
|
||
|
|
Street") returns -32.
|
||
|
|
|
||
|
|
If the first character in the argument (or the first
|
||
|
|
character following all space and tab characters) is a
|
||
|
|
letter, VAL returns 0. Thus, for example, VAL("Yomama")
|
||
|
|
returns 0.
