They've been included after the listing. Perhaps I should have left them outside the code box. Also, their positions have changed:

------------------------------------------

1.745329252E-02 STO 0 ; pi/180
0.199999779 STO 1 ; Five coefficients of the arctangent polynomial -- there are seven of them, 1 and 1/3 are built into the program steps 84, 85 and 88.
0.142841665 STO 2
1.107161127E-01 STO 3
0.086263068 STO 4
0.05051923 STO 5
8.860961462E-07 STO 6 ; Three coefficients of the arcsine polynomial -- the first one is 1 x pi/180 (step 14)
1.349582775E-11 STO 7
9.73259E-17 STO 8

------------------------------------------
Alternatively, but no significant differences:

1745329251 ENTER .99433 + g EEX 10 / STO 0

8860961462 ENTER .4934 + g EEX 16 / STO 6

------------------------------------------
