Ceiling() in less than whole number increments?

[ViciousXUSMC]

Is it possible to do something like Ceiling() and have it round up to say the nearest .04?

Examples:

1.01 = 1.04

1.07 = 1.08

I know in excel you can specify the value in which to increment your ceiling calculations but with autoit it looks like its just to the nearest whole number via decimal point?

Is there something I am missing, or would this require some clever work around with math and other functions?

You'd need to roll your own, or search to see if anyone else has done one previously.

This example appears to work.

ConsoleWrite(_CeilingEx(0.01, 0.04) & @LF)
ConsoleWrite(_CeilingEx(0.07, 0.04) & @LF)
ConsoleWrite(_CeilingEx(0.09, 0.04) & @LF)

ConsoleWrite(_CeilingEx(-0.01, 0.04) & @LF)
ConsoleWrite(_CeilingEx(-0.05, 0.04) & @LF)
ConsoleWrite(_CeilingEx(-0.09, 0.04) & @LF)

;  Round up towards positive infinity.
Func _CeilingEx($n, $x = 0.01)
    Return Ceiling($n / $x) * $x
EndFunc   ;==>_CeilingEx

#cs ; Returns:-
0.04
0.08
0.12
0
-0.04
-0.08

This might not be the fastest solution, but I had fun writing it. You need both this: https://www.autoitscript.com/forum/topic/165558-fraction/ and operator64 in my signature. The simple solution above is best.

My original method (now fixed) is here: https://www.autoitscript.com/forum/topic/165558-fraction/?do=findComment&comment=1283429

#include 'Fraction.au3'

MsgBox(0, "", _CalibrationCeling(1.01, 0.04))

Func _CalibrationCeling($fNumber, $fUnit)
    If $fUnit <= 0 Then Return SetError(1) ; positive values only
    Local $aNum = _Fraction($fNumber)
    If @error Then Return SetError(2) ; NaN
    Local $aUnit = _Fraction($fUnit)
    If @error Then Return SetError(3) ; NaN

    ; same method as above
    $aNum = _FractionMultiply(_FractionCeiling(_FractionDivide($aNum, $aUnit)), $aUnit)
    If Not IsArray($aNum) Then Return SetError(4) ; most likely cause for this error ==> out of bounds
    Return $aNum[0] / $aNum[1]
EndFunc

Actually there was a bug in my original code - I believe the problem was associated with _FractionMod(). I remember having some difficulty with that particular function and being undecided what to do about the problems associated with it - it needs further study. However - changing to the method used by Malkey above seems to be working with fractions (so now the methods are the same), but my new Fraction UDF is still in alpha release stage and I also found (and just fixed) a different bug. I hope I didn't waste too much of anyone's time looking at this. It was time well spent for me to try this out and track down these issues.
