This function exponentiates a quantity x with an associated absolute
error dx using the gsl_sf_result_e10 type to return a result with
extended range.
— Function: int gsl_sf_exp_mult_err_e (double x, double dx, double y, double dy, gsl_sf_result * result)
This routine computes the product y \exp(x) for the quantities
x, y with associated absolute errors dx, dy.
