Expression for n (C):

sqrt( 1 + 0.6961663*pow(x,2)/(pow(x,2)-pow(0.0684043,2)) + 0.4079426*pow(x,2)/(pow(x,2)-pow(0.1162414,2)) + 0.8974794*pow(x,2)/(pow(x,2)-pow(9.896161,2)) )

Expression for n (FORTRAN):

SQRT( 1 + 0.6961663*x**2/(x**2-0.0684043**2) + 0.4079426*x**2/(x**2-0.1162414**2) + 0.8974794*x**2/(x**2-9.896161**2) )

Expression for n (Visual Basic):

SQR( 1 + 0.6961663*x^2/(x^2-0.0684043^2) + 0.4079426*x^2/(x^2-0.1162414^2) + 0.8974794*x^2/(x^2-9.896161^2) )
