CInt(expression)
expression
Use: Required
Data Type: Numeric or String
The range of expression is –32,768 to 32,767; fractions are rounded.
expression cast as an Integer.
Converts expression to an integer; any fractional portion of expression is rounded.
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 0.5, CInt always rounds it to the nearest even number. For example, 0.5 rounds to 0, and 1.5 rounds to 2.
Dim iMyNumber as Integer If IsNumeric(sMyNumber) then iMyNumber = CInt(sMyNumber) End If
When converting a string representation of a number to a numeric, you should use the data type conversion functions—such as CInt—instead of Val, because the data type conversion functions take account of the system's regional settings. In particular, CInt recognizes the thousands separator if it's present in expression, whereas Val doesn't. For example, if expression is 1,234, 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 a number. Also, Fix and Int always return a value of the same type as was passed in.
