DESCRIPTION
DBI(X) calculates the double precision Airy function of the second kind for double precision argument X. Series for BIF on the interval -1.00000E+00 to 1.00000E+00 with weighted error 1.45E-32 log weighted error 31.84 significant figures required 30.85 decimal places required 32.40 Series for BIG on the interval -1.00000E+00 to 1.00000E+00 with weighted error 1.29E-33 log weighted error 32.89 significant figures required 31.48 decimal places required 33.45 Series for BIF2 on the interval 1.00000E+00 to 8.00000E+00 with weighted error 6.08E-32 log weighted error 31.22 approx significant figures required 30.8 decimal places required 31.80 Series for BIG2 on the interval 1.00000E+00 to 8.00000E+00 with weighted error 4.91E-33 log weighted error 32.31 approx significant figures required 31.6 decimal places required 32.90
