Setting precision; [Was] A puzzling arithmetic



Doing this gives the rounded output:

(C6) FPPREC:12;

(D6)                                  12
(C7) FPPREC;

(D7)                                  12
(C8) 57.50+14.95+18.95+8.95+22.95+12.95+7.95+6.95+19.95+12.95+8.95+9.95+16.95
+19.95+11.95
;

(D8)                                 251.8


FPPREC  sets the floating point precision.
