Hum... interesting question. Echo is a simple program, with plenty of options already (man echo for details ^_^).
So I guess it is quite complete already. I never encountered snaggs with echo.0 -

make some nice columns in output:printf "%-20s%s\\n" meh blah printf "%-20s%s\\n" foo bar
round up to a whole number:printf '%0.f\\n' 1.5
convert hex to decimal:printf '%d\\n' 0x100000000
