bug? big number
let variable <a> = 1073741824 / 2
store <a> to the 1st position of a list, alist[1]
let variable <b> = alist[1]
Guess what? <a> does NOT equal to <b>
For example:
let <ai> = log of <a>
let <bi> = log of <b>
let <bib> = 10 ^ <bi>
Now, <ai> is 8.7, <bi> is 0.7, and <bib> is 5.4

Re: bug? big number
You are definately on to something here! I verified your results.
I think what is happening is that when the number gets stored in exponential notation in the list it gets interpreted as a text string by the list. Then, when the value is dumped back into a variable, it looks correct, but internally it is being stored as a text string. So when the the log operator is applied to it, only the numeric portion (before the "e") is being processed by the operator.
Sounds like a bug to me. Good catch!
I put the project that shows the problem here

Oddly enough, it works fine in the Java Player! So it is only a bug in Scratch.
