Clickable SMiley,

FLOAT stands for floating-point number, I believe. A floating-point number is a, in DarkBasic Classic terms, real number. A real number is a value that has numbers to the right side of the decimal point(ex:450.23). Floating-point stands for the decimal point, as if it is moving throughout the numbers.

A real number is simply any non-imaginary number(unlike i)

Think of it as a decimal, with a decimal point. Wherever you need a decimal number with a decimal point, use a float, or a double float.

For most calculations the accuracy is fine. If you get weird results, then consider that they become less accurate, the bigger the numbers you use, and for certain decimal representations.

I would leave it at that, unless you have problems. If you have problems, ask again. It gets very confusing if you've never investigated them before.
