BigNumber comparison

[shmsula]

Tried to compare two big numbers (1000000000000), however only last version works.

Is it correct behavior?

The equality operators use an epsilon to compare numbers, which is 1e-12 by default. You will want to use a smaller epsilon.

See docs: https://mathjs.org/docs/datatypes/bignumbers.html#usage

See also #2608, discussing the introduction of a separate epsilon for bignumbers to prevent the issue you're running into.
