seq \- print sequences of numbers
.SH SYNOPSIS

.I last
.SH DESCRIPTION
.I Seq
prints a sequence of numbers, one per line, from
.I first
(default 1) to as near 
.I last
as possible, in increments of
.I incr
(default 1).
The numbers are interpreted as floating point.
.PP
Normally integer values are printed as decimal integers.
The options are
.TP "\w'\fL-f \fIformat\fLXX'u"
.BI -f format
Use the 
.IR print (2)-style
.I format
.IR print
for printing each (floating point) number.
The default is 
.LR %g .
.TP
.B -w
Equalize the widths of all numbers by padding with
leading zeros as necessary.
Not effective with option
.BR -f ,
nor with numbers in exponential notation.
.SH EXAMPLES
.TP
.L
seq 0 .05 .1
Print 
.BR "0 0.05 0.1" 
(on separate lines).
.TP
.L
seq -w 0 .05 .1
Print
.BR "0.00 0.05 0.10" .
.SH SOURCE
.B /sys/src/cmd/seq.c
.SH BUGS
Option
.B -w
always surveys every value in advance.
Thus
.L
seq -w 1000000000
is a painful way to get an `infinite' sequence.
