#VBA INTEGER OVERFLOW CODE#

Appending the identifier type character & to any identifier forces it to Long.įramework Type. Appending the literal type character L to a literal forces it to the Long data type. This means you can convert Long to any one of these types without encountering a System.OverflowException error. The Long data type widens to Decimal, Single, or Double. If you are passing a 32-bit argument to such a component, declare it as Integer instead of Long in your new Visual Basic code. NET Framework, for example Automation or COM objects, remember that Long has a different data width (32 bits) in other environments. If you are interfacing with components not written for the. Numeric literals can also include the L type character to denote the Long data type, as the following example shows. To use the underscore character as a leading separator, you must add the following element to your Visual Basic project (*.vbproj) file: įor more information see Select the Visual Basic language version. Starting with Visual Basic 15.5, you can also use the underscore character ( _) as a leading separator between the prefix and the hexadecimal, binary, or octal digits.

Starting with Visual Basic 2017, you can also use the underscore character, _, as a digit separator to enhance readability, as the following example shows.

You use the prefix &h or &H to denote a hexadecimal literal, the prefix &b or &B to denote a binary literal, and the prefix &o or &O to denote an octal literal. ' The example displays the following output: In the following example, integers equal to 4,294,967,296 that are represented as decimal, hexadecimal, and binary literals are assigned to Long values. If the integer literal is outside the range of Long (that is, if it is less than Int64.MinValue or greater than Int64.MaxValue, a compilation error occurs. You can declare and initialize a Long variable by assigning it a decimal literal, a hexadecimal literal, an octal literal, or (starting with Visual Basic 2017) a binary literal. Use the Long data type to contain integer numbers that are too large to fit in the Integer data type. IsThisANumber = InputBox('Enter a number less than 32768') It works, but I was hoping there was a more concise way to do it, or even a function already part of VBA that I could use. Also, Fix and Int always return a value of the same type as is passed in. CInt and CLng differ from the Fix and Int functions, which truncate, rather than round, the fractional part of a number. For example, 0.5 rounds to 0, and 1.5 rounds to 2.

So I wrote this code to prevent that from happening. When the fractional part is exactly 0.5, CInt and CLng always round it to the nearest even number. While testing the code I input a number larger than the variable type would allow and I got an variable overflow error. I was writing some code that required the user to input a number, which was then stored in a variable.
