Once upon a time I read that Excel does not use the Integer data type internally. If you use the Integer data type in your code, Excel will convert it to a Long, so you might as well just use Long. It still produces an overflow error if you get outside the Integer bounds, I’ve noticed.
I haven’t used Integer in years because of this, but now I don’t recall who said it and when. It was certainly in a newsgroup post, but I couldn’t google it very easy. Does anyone know if this is true?

How’bout this ?
That’s cool. It doesn’t say why, but Long is consistently faster than Integer.
Thats because Integers are actually converted in the underlying VB Engine. The compilied code is 32 bit, so using Longs skips the under the hood conversion.
InsaneExcel is a cool site, very good kid, check it out, i’ve know about it for time, excel error!
I’m the Who. I post it from time to time so I can’t help with a distinct When.
