Description
|
Converts expression to a
Long
.

Comments
|
This function accepts any expression convertible to a
Long
, including strings. A runtime error is generated if expression is
Null
.
Empty
is treated as
0
.
The passed expression must be within the following range:
–2147483648 <= expression <= 2147483647
A runtime error results if the passed expression is not within the above range.
When passed a numeric expression, this function has the same effect as assigning the numeric expression to a
Long
. Note that long variables are rounded before conversion.
When used with variants, this function guarantees that the expression is converted to a
Long
variant (
VarType 3
).

j& = 123.666
MsgBox "The result of i * j is: " & CLng(i% * j&) 'Displays 12367.
MsgBox "The new variant type of i is: " & Vartype(CLng(i%))
End Sub
