The random and non-random round-off errors in the calculation of 𝜁 can be estimated as a function of number of intervals from assessment of the number of arithmetic operations of each calculation. The code developed by was used to calculate the number of arithmetic operations (FLOPS) for the SAS, considering an average (and constant) 𝑇 1 in the calculation of ℎ $ and 𝐾, for each 𝑘 9CD tested. Then, estimates of random and non-random roundoff errors were performed by multiplying the machine precision (𝜖 m = 2.220446049250313 × 10 0?n ) by FLOPS at the power ½ and 1, respectively ).
