CInt(expression
)
-
expression
Use: Required
Data Type: Numeric or String
The range of
expression
is -2,147,483,648 to 2,147,483,647; fractions are rounded.
Return Value
expression
cast as an Integer
Description
Converts expression
to an Integer; any
fractional portion of expression
is
rounded.
Rules at a Glance
expression
must evaluate to a numeric value; otherwise, a type-mismatch error is generated.If the value of
expression
is outside the range of the Integer data type, an overflow error is generated.When the fractional part of
expression
is exactly .5,CInt
always rounds it to the nearest even number. For example, .5 rounds to 0, and 1.5 rounds to 2.
Example
Dim iMyNumber as Integer If IsNumeric(sMyNumber) then iMyNumber = CInt(sMyNumber) End If
Programming Tips and Gotchas
When converting a string representation of a number to a numeric data type, you should use the data type conversion functions—such as
CInt—
instead ofVal
, because the data type conversion functions take into account the system’s regional settings. In particular,CInt
recognizes the thousands separator if it’s present inexpression
, whereasVal
does not. For example, ifexpression
is 1,234, thenCInt
successfully converts it to the integer value 1234, whileVal
converts it to 1.Use
IsNumeric
to test whetherexpression
evaluates to a number before performing the conversion.CInt
differs from theFix
andInt
functions, which truncate, rather than round, the fractional ...
