Comparing two values, equals or near (how to determine if near?) - (Moved)


Go to solution Solved by water,

Recommended Posts

I'm working on an AutoIt script that pulls in values and compares them in pairs.  I need to know whether two values are either equal or very close to each other.  The latter is what I can't figure out because it's not as simple as a ><= statement and the values are dynamic meaning I need to determine something is near by percentage and not an actual amount.    Is there a function that does this, determines if two values are almost equal based on a global percentage of 2% for example?

Not that I know of.

But you can easily create such a function yourself. 
Quick and dirty: 

$iPercent = 2
Global $iValue1 = 100
Global $iValue2 = 102
Global $iLowerBoundary = $iValue1 - ($iValue1/100*$iPercent)
Global $iUperBoundary = $iValue1 + ($iValue1/100*$iPercent)
if $iValue2 >= $iLowerBoundary And $iValue2 <= $iUperBoundary Then
    ConsoleWrite($iValue2 & " is 'equal' to " & $iValue1 & @CRLF)
Else
    ConsoleWrite($iValue2 & " is NOT 'equal' to " & $iValue1 & @CRLF)
EndIf

Too bad there is no built in function but this is brilliant!  Thanks so much!

Note that the math here could get ambiguous.

Say you want to know whether 98.01 and 100 are "equal" within a 2% range.

Well, 98.01 is 98.01% of 100, so yes, But 100 is 1,0203% of 98, so more than 2% away, so no.

In other words, keep the order of the numbers in mind using this logic.

Roses are FF0000, violets are 0000FF... All my base are belong to you.
