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 ------------------------------------------ Regards, Gerson. |
