Searching for an exact numeric match with a formula

Hi folks, thanks for having me here, my first post after crawling around the internet and looking for answers. You seem the right people to save me!

So here's my situation: I'm running a fairly complex formula to search for AN ID (ID in COLUMN B) in an array (COLUMN G), and return the value of a different column (VALUE in COLUMN H) when found.
However, my formula is giving me a match for partial matches, not exact matches, as such:

If I search for 5.1, it's also returning results for 15.1, or 5.11.

Furthermore, I'd like the results to have a carriage return between them, but it doesn't seem to be working.

I thank you all in advance, and I'm keen to share the knowledge I have y'all.

and I though my formula was complex! :D
Thank you so much for your help mate. I'll break down the formula you wrote and try to learn from it.

Cheers

Hi mate,
Unfortunately the formula you posted worked fine for the sample, but did not work for my original sheet.

The main difference betwee the two is that the original sheet doesn't have tables within it. I tried to replace the table references you have in your formula by the respective ranges, but it didn't work. What am I doing wrong?

Thanks for the heads up. Should I reupload the amended sample then?

I've reuploaded a more accurate example of what I'm trying to achieve. Thank you so much once again.

PS: the original Source spreadsheet is massive. Would there be any issues with memory handling given the amount of text this formula has to parse?

Thanks all, both your answers were very useful and helped me to arrive at the right formula.
