<i>Factor</i> prints <i>number</i> and its prime factors, each repeated the
|
|
proper number of times. The number must be positive and less than
|
|
254 (about 1.8×1016).
|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
|
|
|
|
If no <i>number</i> is given, <i>factor</i> reads a stream of numbers from the
|
|
standard input and factors them. It exits on any input not a positive
|
|
integer. Maximum running time is proportional to <i>-/n </i>.

<i>Primes</i> prints the prime numbers ranging from <i>start</i> to <i>finish</i>,
|
|
where <i>start</i> and <i>finish</i> are positive numbers less than 256. If
|
|
<i>finish</i> is missing, <i>primes</i> prints without end; if <i>start</i> is missing,
|
|
it reads the starting number from the standard input.<br>
