Is there any way for Basic4GL to tell whether a number is a whole number or not/a constant that acts as every whole number?

Maybe something like this:
x=1
y = x + .5
Of course, if there was a "plus or minus" sign, I would use that instead.

B4GL has two types of numbers: integers and reals. An integer is a whole number by definition. Real numbers can have a decimal component. So all you have to do is use the int() function on a variable to see what it would look like as an integer, and if it comes out as a different number than the original, that means the original had a decimal component.
' Returns 1 if num# is whole, 0 otherwise
function iswhole(num#)
if (num# = int(num#)) then
return 1
else
return 0
endif
endfunction

i thought it was in how the variable was dimmed
dim x 'int
dim x#'real
do
cls
printr "x ";x
printr "x# ";x#
x = x + .1
x# = x# + .1
loop
it doesnt show x holding a decimal, only x#,
didnt really think of it the way pizzasgood did...
