Data Types help ... Overflow errors
I have a formula to calculate a percentage,
dim used, guests as Long, result as single result = (USED / GUESTS)*100 and get the dreaded overflow on data type error on some of the answers. I tried double, variant and decimal in the dim statment. decimal wouldn't even take in the dim. then, I tried, result = round((USED / GUESTS)*100,1) but the syntax gets hung up on the parentheses ... help greatly appreciated.

Data Types help ... Overflow errors
Hello Larry
Since one of your variables (guests) used in your calculation is declared as Long (that's between -2 147 483 648 and 2 147 483 647) I can hardly see this working because the "result" variable is declared for a lesser value? Try and declare "result" as long? HTH Cordially Pascal "Larry Levinson" a écrit dans le message de news: ...

Does used or guests exceed figure 2,147,483,647 (i.e. two billions and something)? If not then can result exceed E+38 or can be less than E-45? If not then can guests be zero (0)? Change the code as under and try:- Dim used, guests As Long, result As Single If geusts = 0 Then MsgBox "Zero guests will make it divide by zero _ and cause overflow!" Exit Sub End If result = (used / guests) * 100 Sharad *** Sent via Developersdex http://www.developersdex.com *** Don't just participate in USENET...get rewarded for it! |

In case anyone finds this, it wasn't actually an overflow error. it
was a divide by zero errror masking as an overflow. thanks. Larry Levinson wrote: Overflow ...
