I have 2 questions on floats:
1 What is a float?
2 What is it used for?
I have seen it lately in posts, used help in DBC, but I don't know they can be used for.
Can anyone answer any question (especially #2)
please help me!

1. A float is a number with a floating decimal point, for example, 3.14159265358 (an approximation of pi, from my head). Floats can be 34E +/-38. To use a float variable you can do:



or



Floats can only have 7 digits and whole numbers are more important, so it will cut the decimal off. In the example above, pi,only 3.141592 would be displayed. Example:



a# will print as 1234.567, but b# will print as 123456.7 (the 8 got cut off)

2. Floats are used instead of whole numbers, or integers, to do more presise calculations, fractions, 3D coordinates, and more.
