Post subject:  Just made my account here and Its my first question.
The outpout should look like this :

"The decimal equilent of 1/2 is 0.500
The decimal equilent of 1/3 is 0.300
..
..
The Decimal equilent of 1/10 is 0.100"


I am having difficulty in calling the variables. Its showing an error here.

"var first:=0.5
var last:=0.1
for count: first..last"

"The error is "for range bound must be both integers, chars or elements of the same enumerated type."
What does that mean?


Once I am able to call these variables, Prog will be done. Its showing an error on both real and integer. I would greatly appreciate any help.

it appears that you are trying to have a forloop count from 0.5 to 0.1
code:

for count: 0.5 .. 0.1
 ...
end for

What kind of values would you expect "count" to have, as the loop executes?

This is not working. I have also tried "for decreasing count:0.5..0.1" but still the error is the same. This is killing me.

try something like this

code:

for decreasing i: 5 .. 1
count=i/10
...
end for


this should work, and it gives you your 0.5-0.1 like you want Smile

What Tony means is, what values are in between 0.5 and 0.1? If you were to go through every value, what values would you get?

And back to the error message

Do you know what an integer is? Are either of the bounds on your for loop integers?
