After extending the benchmark file [`/test/benchmark/map.js`](https://github.com/josdejong/mathjs/blob/develop/test/benchmark/map.js), I was triggered by an outlier `abs(array)` which is more than 10x faster than the rest: ``` # develop abs(genericMatrix) x 54,106 ops/sec ±0.59%...

Fix: calculate `log10` for a bigint with value zero (fixes #3539)
