Cant seem to remember how to get round this issue.

Number As float
Number = 100 / 120

Print Number
Wait Key

Returns 0 when what i am after is something like 0.83333333333333 and so on. I know i am missing something, can anyone clarify?

Try this


The reason is that the compiler needs to know to return a float value as you are dividing two Integers, the answer will be an integer. One number must always be a float.

@Kezzla:
Yeah, it's amazing when you think you have a language waxed and then you get these little oddities that jump up and make your life so much easier. Here's a useful thing I picked up on an unrelated thread recently - credits to Chris Tate:
You can return an evaluation to a variable, C-style!


Until then, I thought you could only do that in c++.

Here's the thread:
