1. rand ()

In documentation for rand (x1) function there says:
"Return a random integer from 1 to x1"
Can x1 be returned or not?
Is there some general rule which borders are included and which are
excluded?
Like for example with Rectangle (x1, x2, x3, x4).

rand(x) returns integers in the inclusive range 1 to x.

No, there is no general (rational) rule. The Windows Rectangle function is
weird though. If you specify (left, top, right, bottom), it draws lines
from [left,top] -> [right+1,top] -> [right+1,bottom+1] -> [left, bottom+1] -

Why they didn't make the parameters (left, top, width, height) is beyond my
understanding.
