your tests aren't good: too small, and did you even try several times? You should then notice your results aren't reproducible.

This kind of tiny differences is meaningless because there is the general environment around your tests that is popping up in the values.

tries = 1000000;
v = 1324684352468746354685465463575754687654654656847646874343687448744635468413246843524687463546854654635757546876546546568476468743436874487446354684132468435246874635468546546357575468765465465684764687434368744874463546841324684352468746354685465463575754687654654656847646874343687448744635468413246843524687463546854654635757546876546546568476468743436874487446354684132468435246874635468546546357575468765465465684764687434368744874463546841324684352468746354685465463575754687654654656847646874343687448744635468413246843524687463546854654635757546876546546568476468743436874487446354684132468435246874635468546546357575468765465465684764687434368744874463546841324684352468746354685465463575754687654654656847646874343687448744635468413246843524687463546854654635757546876546546568476468743436874487446354684

using these, I get those timings, in a reproducible way:

• digitize1: 0.002061 milliseconds
• digitize2: 0.002049 milliseconds
