Mat Posted June 16, 2010 Share Posted June 16, 2010 (edited) Yep. Like using floats type variables with 2^x while they where taking about Integer type variable.Wow... never knew that.9187343239835812094 then. (wait... I keep getting different values)Edit: 921886843722740633 ????Edit: dividing does as well.

Mat Posted June 16, 2010 Share Posted June 16, 2010 Kk, last post then I'm done. Dividing also changes the variable to a double. $ni = 61 $n = Int(2 ^ $ni) $i = Int(2 ^ 62) While 1 While Not StringInStr($i + $n, "e") And $i + $n > 0 $i += $n ToolTip($i) WEnd If $n <= 1 Then ExitLoop $ni -= 1 $n = Int(2 ^ $ni) WEnd ToolTip("") ClipPut($i) ; 9223372036854775807 AutoIt Project Listing Link to comment Share on other sites More sharing options...

Moderators Melba23 Posted June 16, 2010 Moderators Share Posted June 16, 2010 jchd,Get what?I just trust what our beloved Devs put in the Help file. If what I quoted from there is wrong, could one of you please put a bug report in Trac, because like wipped - I am not really following. Big numbers always made my head hurt - I much prefer exponentials and limited decimal places. I always thought this summed up the need for accuracy in the real world:Measure it with a micrometer (engineer)Mark it with a pencil (mechanic)Cut it with an axe (workman)M23 Any of my own code posted anywhere on the forum is available for use by others without any restriction of any kind Open spoiler to see my UDFs: Spoiler ArrayMultiColSort ---- Sort arrays on multiple columnsChooseFileFolder ---- Single and multiple selections from specified path treeview listingDate_Time_Convert -- Easily convert date/time formats, including the language usedExtMsgBox --------- A highly customisable replacement for MsgBoxGUIExtender -------- Extend and retract multiple sections within a GUIGUIFrame ---------- Subdivide GUIs into many adjustable framesGUIListViewEx ------- Insert, delete, move, drag, sort, edit and colour ListView itemsGUITreeViewEx ------ Check/clear parent and child checkboxes in a TreeViewMarquee ----------- Scrolling tickertape GUIsNoFocusLines ------- Remove the dotted focus lines from buttons, sliders, radios and checkboxesNotify ------------- Small notifications on the edge of the displayScrollbars ----------Automatically sized scrollbars with a single commandStringSize ---------- Automatically size controls to fit textToast -------------- Small GUIs which pop out of the notification area Link to comment Share on other sites More sharing options...

MvGulik pointed out that's what I was doing wrong when I was using the ^ operator, but it also happens when you divide. Both are because it is likely that the result is a decimal, although in the context of what I was doing they wouldn't be.The one part of that faq that needs to be changed is the line length limit as that is now removed (Or at least part removed...)Mat AutoIt Project Listing Link to comment Share on other sites More sharing options...
