19 .SH DESCRIPTION
20 .I Seq
21 prints a sequence of numbers, one per line, from
22 .I first
23 (default 1) to as near 
24 .I last
25 as possible, in increments of
26 .I incr
27 (default 1).
28 The loop is:
29 .sp
30 .EX
31   for(val = min; val <= max; val += incr) print val;
32 .EE
33 .sp
34 The numbers are interpreted as floating point.
35 .PP
36 Normally integer values are printed as decimal integers.
37 The options are
38 .TP "\w'\fL-f \fIformat\fLXX'u"
39 .BI -f format
40 Use the 
41 .MR print (3) -style
42 .I format
43 .IR print
44 for printing each (floating point) number.
45 The default is 
46 .LR %g .
47 .TP
48 .B -w
49 Equalize the widths of all numbers by padding with
50 leading zeros as necessary.
51 Not effective with option
52 .BR -f ,
53 nor with numbers in exponential notation.
54 .SH EXAMPLES
55 .TP
56 .L
57 seq 0 .05 .1
58 Print
59 .BR "0 0.05 0.1" 
60 (on separate lines).
61 .TP
62 .L
63 seq -w 0 .05 .1
64 Print
65 .BR "0.00 0.05 0.10" .
66 .SH SOURCE

68 .SH BUGS
69 Option
70 .B -w
71 always surveys every value in advance.
72 Thus
73 .L
74 seq -w 1000000000
75 is a painful way to get an `infinite' sequence.
