This can be a way:
awk '{if ($10+0>0) {a+=$10+0} else {b+=$10+0}}
END{printf "positive: %e \nnegative: %e\n", a, b}' file
Where %e
stands for exponential format.
Note that $10+0
expression is done to get rid of the text contained in the field. Hence, 676500000.00SYS
becomes 676500000.00
.
Test
$ awk '{if ($10+0>0) {a+=$10+0} else {b+=$10+0}}
END{printf "positive: %e \nnegative: %e\n", a, b}' a
positive: 1.876500e+09
negative: -1.876500e+09
