The number of iterations (precision) is set via :cpp:member:`cordic_calculate_config_t::iteration_count`. Legal values are 4, 8, 12, 16, 20 and 24. Square root accepts only 4, 8 and 12. Any other value makes the calculation return ``ESP_ERR_INVALID_ARG``. Supported values and their residuals are given below.
