I can declare variables as integer, string, boolean etc but when I try to use "real" the word doesn't get highlighted in blue by the editor and I get a syntax error when I run my code.

e.g.


What am I supposed to use for declaration of decimal variables?

It's actually 'float' - the documentation in that section is just a little out of date.

Thanks, I figured out that it was float eventually by myself .

Hi Treeman & IanM. I've also seen programmers using # in their coding with regards to declaring variables. Is this a recommended practice?

As per this code; I find a few things that I'm still confused with...

Hi Burning Feet Man,

That custom dates back from the Dark Basic Classic compiler. A float was always appended by a # and a string was appended with a $ (nothing was an integer). It allows you to specify the variable's type without actually declaring them. Dark Basic Professional still allows this, so we (I do at least) still make use of that .

Cheers!
Sven B
