lol this is really noobish, but I've never done it before and now that I'm trying to, it's not working as I would have expected. The following code should return 3.5, right?

+ Code Snippet

Test# = 7 / 2
Print Test#

Wait Key

Why doesn't it? And if there's a logical reason, how do I get it to?

Ahh, nice work. Cheers.

The real problem though is that my two numbers are in Integer variables, I guess it would work if I defined them as Real variables but that would mess things up in a different section of code. Ideally I'd like a way to convert them to Real Numbers so I can divide them and get a decimal, is there a command like "Int" for this?

I guess if that fails I can always do it the other way and make them real and use "Int" everytime I need them as integers. Thanks.

Cheat, as long as you introduce a real number into the formula, then answer will be a real number

+ Code Snippet

a=7
b=2
c#=(0.0+a)/b
print c#
wait key

Boo!

+ Code Snippet

Print int(Test#)

Wait Key

Mattman, I'm talking about a 'Real' command, like the equivalent of Int but to make them Real Numbers.

Thanks Spooky, that seems to work.

Also, one last thing (I'm new to these Real numbers lol), is it just me, or are they terribly inaccurate?

+ Code Snippet

Test# = 5.0
Test# = Test# + 0.1

Print Test#

Wait Key

Should return 5.1 logically, but in the code it returns 5.099999990463 - I guess I don't need to be that accurate, but it's still strange.

What you're talking about earlier is casting. You could define your variables as double or float or whatever. Then when you need to use them as an integer, you could use int(variable#). At least I think that's the command. But in DBP, I'm pretty sure the functions do automatic casting.

ive heard that that innacuracy problem is on any language compiler, its a problem with teh CPU and floating point variables not just darkbasic
