Probably a calculation error (MT\930\32)

void OnStart()
{
        int j = 1;
        for ( ulong i = 0; i < ULONG_MAX; i++ )
                j = -j;
        Print( "j=", j ); //результат j=1, а должен быть j=-1
}

I have not calculated it myself, but with even i -> j = -1, and the last i=18446744073709551615/*ULONG_MAX */-1-> even

Tried your script.

The unsetting happens in a moment from joining the graph. It feels like no control is passed to the loop at all.

It feels as if no control is being transferred to the loop at all.

It really does, but it's fast :)

void OnStart()
{
        int j = 1;
        for ( int i = 0; i < INT_MAX; i++ )
                j = -j;
        Print( "j=", j );
}

It's a lot slower...

If I remember correctly, previous versions of the compiler complained when I tried to set

too many iterations in the loop (LONG_MAX and ULONG_MAX) and now the compiler keeps silent...

I have version 910 32 bit.

It's silent and "quick to count" even so:

void OnStart()
{
        int j = 1;
        for ( int i = 0; i < ULONG_MAX; i++ )
                j = -j;
        Print( "j=", j );

Although, supposedly, it should fall into an infinite loop.

He swears where there is no need to swear, and where there is a need to swear, he keeps quiet.

Their manners!

In general, the compiler cannot know the number of iterations.

int f( ulong max )
{
        int j = 1;
        for ( ulong i = 0; i < max; i += ULONG_MAX )
                j = 0;
        return ( j );
}
void OnStart()
{
        ulong max = ULONG_MAX;
        Print( "j=", f( max )); //результат j=1, а должно быть j=0
}

What is true is true. So it's a runtime error.

[Artem Temnikov]

Maybe the for statement doesn't like 8-byte numbers in a tested expression?
