I mostly use floats in my programs, and I wondered:

Let's say I have 20 variables and I want to declare them all as 'floats'.

instead of coding:


Is there a way to group them all together and declare them all at once 'as float' , using the designation 'as float' just once ?

xyx#

The # identifies it as a float.

Just as an FYI, $ identifies the variable as a string.

Sort of, but if you use the symbols, you have to always remember to use the symbol and missing one can be a pain to debug.

x# = 1.0
x$ = "one"
Print(x)
Print(x#)
Print(x$)

Anytime you forget the symbol you will be referring to an integer variable.

in some cases, readability.

force as float
velocity as float
mass as float
gravity as float
size as float

force = mass * velocity

is easier to work with than

phys as float[4]

phys[0] = phys[2] * phys[1]

If you need separate labels for the easy of readability, I'd say writing 20 lines to declare individually labelled floats doesn't seem like too much work. Have you tried making a few arrays to tidy up?



It seems just as simple to remember var[3] as var3. And it makes for easier work down the road with for and if statements.
