PowerBI Report Builder background color expression incorrect result

[arca123]

In Report Builder I have a column that displays percentage. If percentage is less than 100%, I want it to be displayed red, if it's 100% or more - I want it to be displayed green.

I have written this simple expression:

=IIf((Sum(Fields!Sales.Value) / First(Fields!DaysValue)) /(Sum(Fields!Budget.Value) / First(Fields!Days.Value)) < 1,"#E6A5A1", "#A8D5BA")

Fields!Days.Value is always constant, so it shouldn't be breaking the expression.

The expression works as intended, except for when the division is exactly 1. 

What can I do to troubleshoot this? How should I change the expression to get 1= green?

I agree with @GeraldGEmerick, this appears at first glance to be a rounding error.

@arca123 Well, you don't have <= 1 so not sure it is truly 1, maybe it is .99999 and rounding up? Perhaps try < .999 and see if that fixes it.
