.SH DESCRIPTION
|
|
.I factor
|
|
reads lines from its standard input.
|
|
If it reads a positive number,
|
|
.I factor
|
|
will factor the number and print its prime
|
|
factors, printing each one the proper number of times.
|
|
.I factor
|
|
exits when it reads zero, a negative number, or something other than a
|
|
number.
|
|
If a
|
|
.I number
|
|
is given,
|
|
.I factor
|
|
will factor the number, print its prime factors, and exit.
|
|
.PP
|
|
.I primes
|
|
reads a number from the standard input and
|
|
prints all primes larger than the given number and smaller than
|
|
2\u\s832\s10\d (about 4.3\(mu10\u\s89\s10\d). If a
|
|
.I number
|
|
is given,
|
|
.I primes
|
|
will use that number rather than reading one from the standard input.
|
|
.SH DIAGNOSTICS
|
|
`Ouch.' for input out of range or for garbage input.
