Callbacks and types for error estimates

Types for special functions

These type are used by module Sf

type result = {
  1. res : float;
  2. err : float;
}

The result of a computation : res is the value and err an estimate of the absolute error in the value.

type result_e10 = {
  1. res_e10 : float;
  2. err_e10 : float;
  3. e10 : int;
}

Result of computation with a scaling exponent. Actual result is obtained as res *. 10. ** e10.

type mode =
  1. | DOUBLE
    (*

    Double precision : 2 * 10^-16

    *)
  2. | SIMPLE
    (*

    Single precision : 10^-7

    *)
  3. | APPROX
    (*

    Approximate values : 5 * 10^-4

    *)

Reduce the accuracy of some evaluations to speed up computations.
