.TH SERIES 1 "October 24, 1986" "\(co 1980 Gary Perlman" "|STAT" "UNIX User's Manual"
.SH NAME
series \- generate an additive series of numbers
.SH SYNOPSIS
.I series
start end [stepsize]
.SH DESCRIPTION
.I series
prints the real numbers from
.I start
to
.I end,
one per line.
If
.I stepsize
is not specified,
it is assumed to be of unit size.
.I series
begins with
.I start
to which
.I stepsize
is repeatedly added or subtracted,
as appropriate, to approach, possibly meet, but not pass
.I end.
.SH EXAMPLE
.nf
.ta .5i
To make a random permutation of the numbers 1 to 100:
	series 1 100 | perm
or
	series 100 1 | perm
.fi
.SH LIMITATIONS
The reported number of significant digits is limited.
If the ratio of the series range to the
.I stepsize
is too large, several numbers in a row will be equal.

The maximum length of a series is limited to the size of the
maximum long integer that can be represented on the machine in use.
Exceeding this value has undefined results.
