numericValue = VAL(string$)
string$ contains the characters of a number in any of the standard FB formats (decimal, hex, octal or binary),
VAL returns the number's value.
VAL ignores leading spaces in
string$. When it finds a non-space character, it evaluates the remaining characters in
string$ until it encounters a character which is not part of the number. Thus, for example, the string "
3245.6" would be evaluated as 3245.6, but the string "
32W45.6" would be evaluated as 32. If the first non-space character in
string$ can't be recognized as part of a number,
VAL returns zero.
VAL performs the opposite of functions such as
DATA "-3.2", "1.4E2", "&4C1", "9+7" FOR i = 1 TO 4 READ s$ PRINT s$, VAL(s$) NEXT program output: <code>-3.2 -3.2 1.4E2140 &4C1 1271 9+7 9
string$ represents an integer, consider using the
VAL& function, which is faster.
