It's the way it is for speed, I don't think the solution of using the slower API call and catching the exception is better, you still end up with a negative number. Nicer would be to just check if the value overflows |

I have replaced API call with manual overflow checking. |

There was a problem hiding this comment.
I don't understand this test. Should there not 2147483647 atoms here?

Looking back at this I think the simpler solution is to cap the atom count at some upper limit (e.g. 1 million) which is more than enough. TITIN is 35k amino acids https://en.wikipedia.org/wiki/Titin |
