示例2: _big_delta_coeff

def _big_delta_coeff(aa, bb, cc, prec=None):
    r"""
    Calculates the Delta coefficient of the 3 angular momenta for
    Racah symbols. Also checks that the differences are of integer
    value.

    INPUT:

    -  ``aa`` - first angular momentum, integer or half integer

    -  ``bb`` - second angular momentum, integer or half integer

    -  ``cc`` - third angular momentum, integer or half integer

    -  ``prec`` - precision of the ``sqrt()`` calculation

    OUTPUT:

    double - Value of the Delta coefficient
