VAL&
[edit | edit source]Syntax
[edit | edit source]integerValue& = VAL&(string$)
Description
[edit | edit source]This function is similar to the VAL function, but it can only evaluate a string which represents an integer. The advantage of using VAL& is that it executes more quickly than VAL.
string$ can represent an integer in decimal, hex, octal or binary format. The absolute value of the represented integer must not exceed 4,294,967,295.
VAL& ignores leading spaces in string$, and it stops evaluating the string when it encounters a character that is not part of standard integer notation. Note that this means VAL& will stop evaluating the string when it encounters a decimal point or an "E" exponent indicator. That means that certain strings which represent integers will be evaluated differently by VAL than by VAL&. For example, the string "24.61E2" will be evaluated as 2461 by VAL, but as 24 by VAL&.
