seq is missing the -f option:

       -f, --format=FORMAT
              use printf style floating-point FORMAT

For example,

$ seq -f "%.3f" 0 .1 1
0.000
0.100
0.200
0.300
0.400
0.500
0.600
0.700
0.800
0.900
1.000

This could use the code that already exists in printf. I guess that code would need to be moved to uucore so that it could be used by both printf and seq (and others, if any other program requires printf-style string formatting).

seq: implement -f FORMAT option
4fbe2b2 
Add support for the `-f FORMAT` option to `seq`. This option instructs
the program to render each value in the generated sequence using a
given `printf`-style floating point format. For example,

    $ seq -f %.2f 0.0 0.1 0.5
    0.00
    0.10
    0.20
    0.30
    0.40
    0.50

Fixes issue uutils#2616.
