[RESOLVED] Double variables

[Krass]

Hi people.

I might have to do some more debugging on my code but... based on some tests, I'm having strange behabiours with "doubles".

I thought that this might be a general known "issue" and someone would bring up the main causes of that.

My problem is that if I do simple calculations, I end up with a trailing decimal at the 10th position of so.

Exemple: 27.8 - 27.7 will sometimes equal "0.100000000001"

I cound fix my problem my doing round(var,3), but this is just "patching", I don't like it quite much

any idea?

Thanks

That's just the way it is with Doubles. Use Currency instead unless you need more than 4 decimals.

I see. I usually need 3-4 decimals, not more. I'll have to check how many decimals "currency" allows.

Than you're suggesting to use currency, whatever the data I'm dealing with? In my case, it's not currency but quantities, I believe it makes no difference.

Thank you.

I actually updated my post while you were posting to say that you can use up to 4 decimal places, and it doesn't matter if it's not actual currency.

Well that might solve quite a few problems on my side. Thanks for your quick input.

Yes I've been told this a couple of times. The thing is I don't care much about spams getting to THAT hotmail. And I like it when people pops in my live messenger for some coding chat.
