Syntax
CInt(expression
)
-
expression
(required; 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 of Val, 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 in
expression
, whereas Val does not. For example, ifexpression
is 1,234, then CInt successfully converts it to the integer value 1234, while Val converts it to 1.Use IsNumeric to test whether
expression
evaluates to a number before performing the conversion.CInt differs from the Fix and Int functions, which truncate, rather than round, the fractional part of ...
