[Solved]_Chess table 64 squares * 2

Recommended Posts

goldenix

I tried to prove a formula, but it did not work. then I ran the loop 62 times & multiplied manually by 2 twice & got correct answer: 18446744073709551616

Is this autoit bug?

Im tying to multiply each square by 2 & then multiply the answer by 2. we get this:

2

4

8

16

32

64

128 etc...

18446744073709551616

$c = 1
For $a=1 to 64
    $x = _main($c)
    ConsoleWrite($x & @CRLF)
Next



Func _main($B)

    $c = $b*2
    
    Return $c
EndFunc

Integers are limited to 64-bit, you're surpassing this limit.

$c = 1.0
For $a=1 to 64
    $x = _main($c)
    ConsoleWrite($a & @tab & $x & @CRLF)
Next

Func _main($b)
    $c = $b*2
    Return $c
EndFunc

Until iteration 62 is working:

$x = 1
For $i = 1 To 64
    $x = $x * 2
    ConsoleWrite($i & ": " & $x &  @CRLF)
Next
ConsoleWrite ("Max. 64-bit = " & 2^64 -1 & " (18446744073709551615)" &  @CRLF)

As KaFu said the 64-bit limit will be exceeded.
