Why do FOR/NEXT variables end up +1 more?

[DSMan195276]

It's because

FOR

works by first incrementing the loop variable and then checking if it is greater than the end value you gave. For your loop, the first time

t

is greater is when it is incremented to 11.

The reason it works this way is because depending on your

STEP

and what end number you use, you might not hit the last number at all and instead skip right over it. Imagine you did this:

Code: (Select All)

For t = 1 To 10.5 Step 1

Next

Print t ' What should t be?

Obviously

t

cannot be 10.5 at the end because 10.5 will never be hit by the loop. Instead it works identical to your loop,

t

gets incremented to 11 and since that's greater than 10.5 the loop stops there.
