Int, Fix Functions

Returns the integer portion of a number.

Syntax

Int( number )

Fix( number )

The required number argument is a Double or any valid numeric expression. If number contains Null, Null is returned.

Remarks

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))

This example illustrates how the Int and Fix functions return integer portions of numbers. In the case of a negative number argument, the Int function returns the first negative integer less than or equal to the number; the Fix function returns the first negative integer greater than or equal to the number.

Dim MyNumber
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.
MyNumber = Fix(-99.2)    ' Returns -99.
