gives the arithmetic‐geometric mean of a and b.
- For certain special arguments, ArithmeticGeometricMean automatically evaluates to exact values.
- ArithmeticGeometricMean can be evaluated to arbitrary numerical precision.
- ArithmeticGeometricMean is a homogeneous function of a and b, and has a branch cut discontinuity in the complex plane, with a branch cut running from to 0.
- ArithmeticGeometricMean automatically threads over lists.
