Hi,
I want to calculate the difference between two dates and the result should be in Months with values upto two decimal places.

If I am using the "DATEDIF" Function then it is truncating the results and not provinding the results updo two decimal places.

Can you please suggest any function available in webfocus 7.6.11 Version.
Thanking you.

I don't think you can work with decimals and dates. What does 1.2 months mean? You could extract days or hours or smaller measures and do the division yourself...

True!

What is a month ?, 31, 30, 28 days ?, 365 / 12 days ?, 365.25 / 12 days ?

Also what code did you use ?

Francis I agree with you that it does not mean to have month like 1.2, but this is our business requirement.
We have to first calculate the month and then find out the average of all the records.
If I am using DATEDIF function,the result deviated from its actual value.

Also I have thought of first finding the number of days and then dividing by 30.4, but its a kind of approximate method.
If you find any solution please let me know.

Many Thanks.

You could base the decimal portion on a list of (days in months). and go from there.

(days in month list) = (1 31 2 28 3 31...) with an offset for leap year. Use (day of month) in you calculation with the associated days from your list...

I hope this helps. Smiler

When we have to do this, this is how we do it:
MONTHS/D8.2=(HIGH_DATE-LOW-DATE)/30.4375;


This truncates to 2 digits.

If you want automatic rounding use the P format.

According to the documentation, using HDIFF requires using a D format (Floating Point Double Precision). All the examples show D12.2. However, it does not return fractions either. I asked IBI why have the 2 decimals if they are never used? They did not know so I put in a NFR. So that existing code would not be changed, I suggested using FDAY, FYEAR, etc. in the types for fractional days, years, etc.

It is in "Product Division" whatever that means. If you have a use for fractional date/time computations with DATEDIF or HDIFF, please do a NFR.

If you're coding a fractional month to a specific business requirement, then that business unit needs to provide you with their official calculation method.

It may be as simple as number of days divided by 30, it may be some strange arcane thing based on the phase of the moon. Regardless, that business unit calls the tune on their expected value. Contact them and ask for the official version. Without it you'll never clear their testing.
