Hi Charles,<o:p></o:p>
Thanks for your reply. This function does work for +ve values but for ?ve values it?s giving wrong result.<o:p></o:p>
I think for ?ve value we need to put some extra logic.<o:p></o:p>
<o:p> </o:p>
q)myfloor -2147483647.0000<o:p></o:p>
-2147483648j<o:p></o:p>
q)floor -2.00<o:p></o:p>
-2<o:p></o:p>
<o:p> </o:p>
You can see in above example for -2.00 we are getting the floor as -2 in the same way for -2147483647.0000 we should get -2147483647 instead of -2147483648.<o:p></o:p>

Hi,
When I run the following command I am getting o/p as 0W.
q)floor 2147483647.21434f
0W
q)floor 6347291066f
0W
As I can understand it’s because floor returns the int value and the above command returns the value which Is bigger than int.
I am looking for the solution where instead of int my floor function should return long value.
Is there any way to make floor return the long value instead of int?
Thanks for your help in advance.

Can you try this
myfloor:{$[0 = x mod 1; :“j”$x; :“j”$x-.5]}
?
regards,
?
With all the use kdb+ gets in the money game, there must be some material showing the floor family of functions. Have you looked at the wiki at code.kx.com ?
myfloor2:{“j”$x div 1}
should work
q){“j”$x div 1} -2147483648.1
-2147483649j
q){“j”$x div 1} -2147483648.0
-2147483648j
