<P>
When the <em>ifactor</em> switch is on, any integer terms appearing as a result
of the
<A HREF=r37_0151.html>factorize</A> command are factored themselves into primes.
Default
is <em>off</em>. If the argument of <em>factorize</em> is an integer,
<em>ifactor</em> has no effect, since the integer is always factored.

factorize(4*x**2 + 28*x + 48);

factorize(4*x**2 + 28*x + 48);
{{2,2},{X + 4,1},{X + 3,1}}
factorize(22587);
{{3,1},{7529,1}}
</TT></PRE><P>Constant terms that appear within nonconstant
polynomial factors are not factored.

The <em>ifactor</em> switch affects only factoring done specifically
with
<A HREF=r37_0151.html>factorize</A>, not on factoring done automatically when th
e
<A HREF=r37_0287.html>factor</A> switch is on.
