A regular itchy annoyance for years now: df shows bytes, df -h shows only one decimal place, so e.g. on a 1.8TiB drive "1.6T" is the free space, but that resolution/ precision is insufficient. Of course I can fire up bc, set scale=20 and do some powers of 1024 division, but that's all very clunky.
How hard would it be to add an option to bc, to choose the number of decimal places to use in the output, or the number of digits of precision to display? TIA,
