seq – print sequences of numbers

seq [ –w ] [ –fformat ] [ first [ incr ] ] last

Seq prints a sequence of numbers, one per line, from first (default 1) to as near last as possible, in increments of incr (default 1). The loop is:
for(val = min; val <= max; val += incr) print val;
The numbers are interpreted as floating point.

Normally integer values are printed as decimal integers. The options are
fformat    Use the print(2)–style format print for printing each (floating point) number. The default is %g.
w        Equalize the widths of all numbers by padding with leading zeros as necessary. Not effective with option –f, nor with numbers in exponential notation.

seq 0 .05 .1
Print 0 0.05 0.1 (on separate lines).
seq –w 0 .05 .1
Print 0.00 0.05 0.10.


Option –w always surveys every value in advance. Thus seq –w 1000000000 is a painful way to get an `infinite' sequence.
