CInt Function
Returns an expression that has been converted to a Variant of subtype
Integer.
CInt(expression)
The expression argument is any valid expression.
Remarks
In general, you can document your code using the subtype conversion functions
to show that the result of some operation should be expressed as a particular
data type rather than the default data type. For example, use CInt or
CLng to force integer arithmetic in cases where currency,
single-precision, or double-precision arithmetic normally would occur.
Use the CInt function to provide internationally aware conversions
from any other data type to an Integer subtype. For example, different
decimal separators are properly recognized depending on the locale setting of your system, as are different thousand separators.
If expression lies outside the acceptable range for the Integer
subtype, an error occurs.
The following example uses the CInt function to convert a value to an
Integer: Dim MyDouble, MyInt
MyDouble = 2345.5678 ' MyDouble is a Double.
MyInt = CInt(MyDouble) ' MyInt contains 2346.
Note CInt differs from the Fix and Int
functions, which truncate, rather than round, the fractional part of a number.
When the fractional part is exactly 0.5, the CInt function always rounds
it to the nearest even number. For example, 0.5 rounds to 0, and 1.5 rounds to 2.
