I am trying to determine whether a number is a whole number or not.

If I try to compare the number to it's integer equivalent (i.e. var# = int(var#) ) I always get true - even if var# contains 1.0234 or whatever.

It's driving me around the twist!

Any help would be appreciated.

Yeah, that should work...That is how I would do it...

Are you sure that you are using a float and not an interger (I don't think you are stupid, I do stupid stuff too, you can't bee too careful)

ex:
var=int(var)

vs

var#=int(var#)

As far as I can tell I am comparing a float to an integer - when I print the variable I consider a float it does include the decimal point and fraction components - I'll go back through and have another look through as this has to be something immensely elementary that I am doing wrong.

Thanks for the assistance - I am very new to DBPro (not programming itself).

OK Something really odd going on here.

I tried just Trowbee's snippet in a brand new blank program and when I ran it, I got the same value for Int(v#) and (Int(v#)=v#) - both times it returned 1.

My own snippet in a blank brand new program also gets 1 as the result of both comparisons.

This really is driving me nuts.

I was running the original version of Darkbasic Professional as installed from the CD - I have just updated to 1.052 and the calculations are now working as expected.

Thanks to everyone who helped me on this - at least I know it wasn't me going around the twist!
