Wait till you include floating numbers.
"There are an infinite numbe of numbers between any two natural numbers"
So technically you could increase that percentage to 99.9999....%
A few calculations I did last time I saw this meme (over at ![email protected]):
There are 9592 prime numbers less than 100,000. Assuming the test suite only tests numbers 1-99999, the accuracy should actually be only 90.408%, not 95.121%
In response to the question of how long it would take to round up to 100%:
The density of primes can be approximated using the Prime Number Theorem: 1/ln(x).
Solving 99.9995 = 100 - 100 / ln(x) for x gives e^200000 or 7.88 × 10^86858. In other words, the universe will end before any current computer could check that many numbers.

I think a more concise answer to the second one would be; it depends on where you decide to round, but as you run it, it approaches 100%, or 99.99 repeating (which is 100%)
The screenshot displays 3 decimal places, which is the the precision I used. As it turns out, even just rounding to the nearest integer still requires checking more numbers than we even have the primes enumerated for (e^200 or 7x10^86)

You don't even need floats for that. Just increase the amount of tests.
Actually it would approach 100% without ignoring data wouldn’t it?

Ah, ok yeah that makes sense.
By the prime number theorem, if the tests go from 1 to N, the accuracy will be 1 - 1 / ln(N). They should have kept going for better accuracy.

Aw man, my prime number classifier is only 4.879% accurate. :(
