Int
Description Returns the integer portion of a number
Usage intVal = Int(number)
Arguments number
The number argument can be any valid numeric expression.
Return An integer value
Remarks If number contains Null, Null is returned. Int is internationally aware, meaning the return value is
based on the Locale setting on the PC. The data type will be determined from the size of the
Integer part. Possible return data types are Integer, Long, Double.
Both Int and Fix remove the fractional part of number and return the resulting integer value.
The difference between Int and Fix is that if number is negative, Int returns the first negative
integer less than or equal to number, whereas Fix returns the first negative integer greater than
or equal to number. For example, Int converts -8.4 to -9, and Fix converts -8.4 to -8. Fix(number)
is equivalent to: Sgn(number) * Int(Abs(number)).
See also Fix, Round, CInt, CLng
Example MyNumber = Int(99.8) ' Returns 99.
MyNumber = Fix(99.2) ' Returns 99.
MyNumber = Int(-99.8) ' Returns -100.
MyNumber = Fix(-99.8) ' Returns -99.
MyNumber = Int(-99.2) ' Returns -100.
IsArray
Description Returns a Variant subtype Boolean value indicating whether a variable is an array
Usage result = IsArray(varname)
Arguments varname
The varname argument can be any variable subtype
Returns IsArray returns True if the variable is an array; otherwise it returns False.
See also IsDate, IsEmpty, IsNull, IsNumeric, IsObject, and VarType
Example Dim MyVariable
Dim MyArray(2)
MyArray(0) = “Sunday”
MyArray(1) = “Monday”
MyArray(2) = “Tuesday”
MyVariable = IsArray (MyArray) ‘ MyVariable contains True
IsDate
Description Returns a Boolean value indicating whether an expression can be converted to a valid date.
Usage boolVal = IsDate(expression)
Arguments expression
The expression argument can be any date expression or string expression recognizable as a
date or time.
Remarks IsDate returns True if the expression is a date or can be converted to a valid date; otherwise, it
returns False. In Microsoft Windows, the range of valid dates is January 1, 100 A.D. through
December 31, 9999 A.D.; the ranges vary among operating systems.
See Also CDate, IsArray, IsEmpty, IsNull, IsNumeric, IsObject, VarType
Example The following example uses the IsDate function to determine whether an expression can be
converted to a date:
Dim MyDate, YourDate, NoDate, MyCheck
MyDate = "October 19, 1962"
YourDate = #10/19/62#
NoDate = "Hello"
MyCheck = IsDate(MyDate) ' Returns True.
MyCheck = IsDate(YourDate) ' Returns True.
MyCheck = IsDate(NoDate) ' Returns False.
