After 150+ iterations, iterations stops and gives an error FLOATING POINT ERROR :INVALID NUMBER

What does this indicate? Plz let me know Thanks

The errors that are either because of invalid numeric computation initiated by you or limitation of ur pc or u have a data with small or large magbitude . i dont know what ur cases but these are the answers for ur questions i guess .

Thanks,H.A.S. i wll chck

If that doesn't work try changing the number type(REAL,INT,etc) on any udf you may have to a better description. Probably FLOAT to DOUBLE. I think that was the error message I got when I had written a udf slightly wrong.

Phil, I change the type also. But still gives error

Thanks Ralf, Error problem got solved

I've had this problem before but don't know if it's for the same reason as you and can't really remember how I fixed it but - There are afew good udf examples in the udf user guide. If you rummage through them and find one with similar numbers/structure/commands then comparing them usually fixes any problems.

IF YOU CAN'T FIND ANYTHING YOU SHOULD PASTE THE CODE ONTO A MESSAGE, THERE'S LOTS OF PEOPLE READING WHO HAVE HAD SIMILAR PROBLEMS AND MAY BE ABLE TO SUGGEST A SOLUTION.
