Small Basic: Iteration Count


Take a look at this For loop:

For N = i To t Step s

  Statement(s)

EndFor

 

i is the initial value, t is the terminal value, and s is the step size. You can use this formula to find the number of times your program runs the loop (the iteration count):

 

 

 
The answer’s truncated (if needed) to give you an integer; the decimal part is removed. Of course, the minimum iteration count’s zero. This table shows you some examples:

Example

i, t, s

Formula

Iteration Count

For N = 1 To 20 Step 3

1, 20, 3

7.33

7

For N = 5 To 150 Step 40

5, 150, 40

4.625

4

For N = 20 To 5 Step –3

10, 5, –3

6

For N = 2.5 To 8.0 Step 0.5

2.5, 8.0, 0.5
