How does splunk handle decimal value?

Hi!

I would like to know how does splunk handle the decimal values during eval procesing.

It seems that after the eval(multiplication or division) , the number is rounded to 6digits.

So if the result is 1.123456789, it would be 1.123456.

Is there, rules in splunk for handling decimal number?

Since its crucial issue, any advice is appreciated!

Thanks, Yu
