If you want the reverse operation, convert a date to the number in the same format as above, this should work:

=year(date)-1900 & (date - yearstart(date))+1

in this case i try this

((date(yearstart(makedate((((SLTRDJ - fmod(SLTRDJ,1000)) / 1000) + 1900))) + (fmod(SLTRDJ,1000) - 1)) as Date,)

but when i need to convert a normal date to a numeric value it not converted .

Isn't it the same question that I answered here: Re: Date &amp; Calender

The solution was

=date(makedate(left(SLTRDJ,3)+1900) + right(SLTRDJ,3)-1)
