CLng Function

將任意字串型表示式或數值型表示式轉換為長型整數。

Syntax:


CLng (Expression As Variant) As Long

Return value:

Long

Parameters:

Expression: Any string or numeric expression that you want to convert. To convert a string expression, the number must be entered as normal text using the default number format of your Collabora Office locale settings. For instance, the number must be entered using a dot "." as the decimal point and a comma "," as the thousands separator (for instance 123,456.78) for the English locale setting.

If Expression lies outside the valid long integer range between -2.147.483.648 and 2.147.483.647, Collabora Office Basic returns an overflow error.

此函式總是將數字的小數部份取整為最接近的整數。
