Introduction The implementation of a math function, such as cos(::Float64) in Julia, should be fast, but also needs to be at least somewhat accurate. Here I propose a method for visualizing empirical accuracy data. Consider the discrepancy between the exact value of a univariate real function, such…

Love your approach of using low-discrepancy sequences!
