Revit 2008 

Does anyone have any way of determining if the true value of a parameter is an integer or a real eg 4 or 4.2.

If this was in a if statement it would be perfect

This is theoretical...sorry don't have time to fully test it, but here goes:

Make a parameter that is an Integer type. Set its formula to be equal to the Parameter you are checking. It should round off any fractions. Then you can make a parameter with an IF statement that checks whether your original value and the "integer"ized value are equal...if they are, then the original was an integer to begin with, if no...it wasn't.

Just taking a shot.

I have been using this for Arrays.  I needed to return an Integar value, not a rounded value.  Revits Integar isn't technical correct.  Using the INT command in other programs will return 5.9 as 5 where Revit will return 6.

I have be using this to figure out complete sheets (4'x8' sheets).  I have two family parameters, one is Number type and one is Integar, they are both calculated off the equation (which is Dimension to be Covered divided by Sheet Width)

If(Number > Integar, Integar , Integar -1)

 -1 takes the 5.9 rounded to 6 back down to 5,  as an integar should be

If all you need is for Revit to always round up, that's a lot easier. Using your example make an integer type parameter with formula

= Length / Sheet Width + .4999

5.3 becomes 5.7999 and reports as 6...5.7 becomes 6.1999 and reports as 6.  It's .4999 and not simply .5 in case Length divided by Sheet Width returns an integer in the first place it will round back down to the integer.
