How to count the number of years between two dates

Question

Hi friends,

I will rest my question because I did not turn the good answer

I want to calculate the number of years between start date and end date in crystal report

I have tested many functions in crystal report like this one DateDiff ("yyyy", {decompte.Date_demarrage}, {decompte.Date_fin}): in case the number of years = 1 it shows me 1.00

In case of the number of years <1 it shows me for example 260

I do not want it like that I want when the number of years == 1 shows me 1

When the number is less than 1 it shows me 1 and so on

I will be very happy if I find someone who can help me

And thanks in advance friends
