Question

How can I cast a long to double in VBA ? I have googled here and there, and saw some ugly things such as

dim i as long
i = 100
dim d as double
d = i * 1.00000000001

I haven’t tested this, I guess this is working, but my application is really data sensitive and I’d like to actually have a cast with no effect on data… Does that not exist ?

You don’t need to “cast” anything, this will work fine

dim i as long
dim d as double
i = 100
d = i

(and it took me about 30 seconds to start Excel, press ALT-F11, and test it).
