It's fun to make an own commify.
Code:
printf "%.f\n" "$FLOAT" |
sed '
  /\./!s/$/./
  :Loop
  s/\([0-9]\)\([0-9]\{3\}[.,]\)/\1,\2/
  t Loop
  s/[.]$//
'

Or with good locale:
Code:
$ LC_NUMERIC="C" /usr/bin/printf "%'.f\n" "1.14475E+15"
1144750000000000
$ LC_NUMERIC="POSIX" /usr/bin/printf "%'.f\n" "1.14475E+15"
1144750000000000
$ LC_NUMERIC="fr_FR.utf8" /usr/bin/printf "%'.f\n" "1.14475E+15"
1 144 750 000 000 000
$ LC_NUMERIC="en_AG.utf8" /usr/bin/printf "%'.f\n" "1.14475E+15"
1,144,750,000,000,000

PS: Don't believe ' in format string %'.f\n.
