Conditional Formatting to VBA

So I have the code below working that if the cells value in column K is less than Column E *.10 then the cell in column K turns red.

It is working for every line except line 31, cell K is equal to cell E but it is still making it red, I can't figure out why.

Sub setCondFormat()
Range("K13:K42").Select
With Range("K13:K42")
.FormatConditions.Add Type:=xlExpression, Formula1:= _
"=IF($K13="""",FALSE,IF($K13 < $E13*.1,TRUE,FALSE))"
With .FormatConditions(.FormatConditions.Count)
.SetFirstPriority
With .Interior
.PatternColorIndex = xlAutomatic
.Color = 255
.TintAndShade = 0
End With
End With
End With
End Sub

Look at the 2nd line, unless my mental math is just wrong.

Are the numbers in Row K rounded? If I type 949.70 its not red. If I type 949.71 or higher, it's not red. If I type 949.699, it displays 649.70 in Red.

It is pulling from the formula =E31-I31-J31

Where E is the sum of two numbers, no more than 2 decimal palces. I is 0.9*F, which is currently 0. And J is G*.9, which comes to exactly 8,547.30. So no rounding should be taking place.

When working with percentages, there's always a rounding factor. keep expanding the decimals in K31, and you'll eventually see it change down to 949.699999999999. (Even though you have it set to 2 decimals)

Well then, is there anyway around this?

Sadly, I can't come up with anything at this moment. I was thinking if you could somehow have the data in J pasted as a rounded value, it may help, but what's funny is if I manually type in these exact values:
9497.00 (in column E) and 8547.30 in column J, and set K= E minus J, I get 949.7000000000001. Not sure where that little 1 is coming from. All cells are formatted as numbers.
