it recomended to use the builten function _DateDiff hello autoit team i made a simple function to help me get the difference between to date i liked to share it with you the paramatrs of this function is firstdate and lastedate the two params is as the following year/month/day hours:minuts:seconds here is the function #include <date.au3> func _dateBetween($s_firstDate, $s_lastDate = default) if not (StringRegExp($s_firstDate, "((\d{4})\/(\d{2})\/(\d{2})\s(\d{2})\:(\d{2})\:(\d{2}))", 0) = 1) then Return SetError(1, 0, 0) if $s_lastDate = default then $s_lastDate = @year & "/" & @mon & "/" & @mday & " " & @hour & ":" & @min & ":" & @sec if not (StringRegExp($s_lastDate, "((\d{4})\/(\d{2})\/(\d{2})\s(\d{2})\:(\d{2})\:(\d{2}))", 0) = 1) then Return SetError(2, 0, 0) local $a_FirstSplitDate = StringSplit(StringRegExpReplace($s_firstDate, "((.*)\s(.*))", "$2"), "/", 2) local $a_FirstSplitTime = StringSplit(StringRegExpReplace($s_firstDate, "((.*)\s(.*))", "$3"), ":", 2) local $a_lastSplitDate = StringSplit(StringRegExpReplace($s_lastDate, "((.*)\s(.*))", "$2"), "/", 2) local $a_LastSplitTime = StringSplit(StringRegExpReplace($s_lastDate, "((.*)\s(.*))", "$3"), ":", 2) local $i_firstDateValue = _DateToDayValue($a_FirstSplitDate[0], $a_FirstSplitDate[1], $a_FirstSplitDate[2]) local $i_LastDateValue = _DateToDayValue($a_LastSplitDate[0], $a_LastSplitDate[1], $a_LastSplitDate[2]) if $i_firstDateValue > $i_LastDateValue then Return SetError(3, 0, 0) local $i_totalDays = $i_LastDateValue-$i_firstDateValue if not ($i_totalDays = 0) then if $a_FirstSplitTime[0] <= $a_lastSplitTime[0] then $i_totalDays += 1 $a_lastSplitTime[0] -= $a_FirstSplitTime[0] elseIf $a_FirstSplitTime[0] > $a_lastSplitTime[0] then if $i_totalDays > 0 then $i_totalDays -= 1 $a_FirstSplitTime[0] -= $a_lastSplitTime[0] endIf endIf endIf local $i_totalYears = 0 if $i_totalDays >= 365 then While $i_totalDays >= 365 $i_totalYears += 1 $i_totalDays -= 365 Wend endIf local $i_TotalMonths = 0 if $i_totalDays >= 30 then While $i_totalDays >= 30 $i_totalMonths += 1 $i_totalDays -= 30 Wend endIf local $i_totalWeeks = 0 if $i_totalDays >= 7 then While $i_totalDays >= 7 $i_totalWeeks += 1 $i_totalDays -= 7 Wend endIf $i_totalSeconds = ((($a_FirstSplitTime[0]*60)*60)+($a_FirstSplitTime[1]*60)+($a_FirstSplitTime[2]))-((($a_lastSplitTime[0]*60)*60)+($a_lastSplitTime[1]*60)+($a_LastSplitTime[2])) local $minus = "" if $i_totalSeconds < 0 then $minus = "-" $i_totalSeconds = StringReplace($i_totalSeconds, "-", "") endIf local $i_totalHours = 0 if $i_totalSeconds >= 3600 then While $i_totalSeconds >= 3600 $i_totalHours += 1 $i_totalSeconds -= 3600 Wend endIf local $i_totalminuts = 0 if $i_totalSeconds >= 60 then While $i_totalSeconds >= 60 $i_totalminuts += 1 $i_totalSeconds -= 60 Wend endIf local $a_arrayReturn[7] $a_arrayReturn[0] = $i_totalYears $a_arrayReturn[1] = $i_totalMonths $a_arrayReturn[2] = $i_totalWeeks $a_arrayReturn[3] = $i_totalDays $a_arrayReturn[4] = $minus & $i_totalHours $a_arrayReturn[5] = $minus & $i_totalminuts $a_arrayReturn[6] = $minus & $i_totalSeconds return $a_arrayReturn endFunc here is an example $a_calc = _dateBetween("2015/02/12 23:00:05", "2030/02/12 23:25:50") msgBox(64, "result", StringFormat("the difference is : %i years and %i months and %i weeks and %i days and %i hours and %i minuts and %i seconds", $a_calc[0], $a_calc[1], $a_calc[2], $a_calc[3], $a_calc[4], $a_calc[5], $a_calc[6])) am waiting for your comments with my greetings

Hello all! I use Autoit for a while, already made some automation for a TV station's master control room with it.

Reverse Polish Notation (RPN) is a math notation in which each operator follows its two operands. I own an HP 48G calculator which uses RPN, and when I tried to use the windows calculator I had so much trouble that I wrote my own calculator. Basically, it has a stack of numbers; any time an operator is pressed, that operation is carried out immediately on the two items on the bottom of the stack, or the stack and the input if there is anything in the input. This method reduces the requirements for parenthesis and makes calculating equations/functions relatively easy: instead of (sqrt(5+8))/(8*9) you would enter 5 ENTER 8 + SQRT 8 ENTER 9 * / Practical implications Suggestions/advice/criticisms are greatly appreciated! calc2.au3

hi everyone! I need some help with my rpn calculator. I first translated it from vbscript to autoitscript and that's when i stumbled on problem one: (46) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.: $Stack[ubound($Stack)] = $Item ^ ERROR After that (and i know this from testing it as a vbscript) it can't work with negative numbers: "1 - - 2" to Reverse Polish notation = "1 - 2 -" gives me the build in error...

Here's a graphing calculator I've been making, It can graph most functions and solve basic derivatives and integrals I haven't gotten around to making functions for solving indefinite integrals yet, and i know that my derivative functions don't work for all types of functions. please post any feedback, BuckMaster Graphing Calc.rar
