Looks like you need either:

1. a tolerance on the comparison
   or
2. some rounding when generating the numbers in the sequence

If I understand you, you want the numbers whose last decimal digit is an even number:

<— not a GH expert so I’m making some assumptions about how the components in the screenshot work.

My assumption had been that he wanted numbers which “should” be even, such as 8.0 in his screenshot, to make it through the list.

Because he’s interpolating between values by adding a non-integer increment between them, sometimes the answer isn’t “quite” right.

In the screenshot, his 4.0 is “close enough” to 4 for the comparison to succeed but 8.0 is probably something like 7.99999 and fails.
