FLOAT defines a type of number eg. an INTEGER is a whole number. Look it up on any wensite to do with programming, it is pretty standard no matter what the language.

Don't bother with float, use real numbers by declaring them with a # symbol after the variable name; eg: number#=3.141

Konrad, that's pretty strict advice, I'd like to hear why you suggested that to dax24 ?

The info is a bit hard to locate in the dbpro help files.
Help > main menu > principles > data types and variables.
That help pages refers to floats as reals for some reason.

There is also a tutorial specifically about the data types in dbpro.

Yeh I would like to know aswell, I've always thought as Float and Real being the same (they may take up different amounts of memory im not sure ) This also brings up another point which I never thought about until now what about if you add a '#' to a variable but then declare it as an integer? does it get over written?

Example

Global Number# as integer

I've personally always used floats but maybe after you explaining why using real numbers is better i'll change

There is no difference between a real and a float in DBPro.

When you define a variable with a # as an integer, it gets treated as an integer.

For free Plug-ins, source and the DBPro Interface library for Visual C++ 6 and .NET

I declare the variable as float in this example (and always) as the editor (Twilight) I use can list the variables that I have declared, so I can see them easily. I can also refer to the code to see the variables. I completely disagree with konrad, it's bad practice not to declare variables.

Do you bite your thumb at me sir?

Yeh I never used to declare variables, but now I use alot of functions so I always declare them, but I'm straying off topic.

These were the 2 points I was getting at:

from IanM:
Quote: "There is no difference between a real and a float in DBPro.
"


from Hamish:
Quote: "I completely disagree with konrad, it's bad practice not to declare variables"


I couldn't agree more and would take these points a slight step further and would say that you should always try and use some form of Hungarian Notation (imho)

intMyVar as Integer
fltMyVar as Float
etc
