===Computational complexity===
{{main|Computational complexity of mathematical operations}}
The [[Computational complexity theory|computational complexity]] of computing the natural logarithm using the [[Arithmetic–geometric mean|arithmetic-geometric mean]] (for both of the above methods) is <math>\text{O}\bigl(M(n) \ln n \bigr)</math>. Here, {{mvar|n}} is the number of digits of precision at which the natural logarithm is to be evaluated, and {{math|''M''(''n'')}} is the computational complexity of multiplying two {{mvar|n}}-digit numbers.
