IFACTOR _ _ _ _ _ _ _ _ _ _ _ _ switch

When the ifactor switch is on, any integer terms appearing as a result of the factorize command are factored themselves into primes. Default is off. If the argument of factorize is an integer, ifactor has no effect, since the integer is always factored.

examples:

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

  {{4,1},{X + 4,1},{X + 3,1}} 


factorize(22587); 

  {{3,1},{7529,1}} 


on ifactor; 

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

  {{2,2},{X + 4,1},{X + 3,1}} 


factorize(22587); 

  {{3,1},{7529,1}} 

Constant terms that appear within nonconstant polynomial factors are not factored.

The ifactor switch affects only factoring done specifically with factorize, not on factoring done automatically when th e factor switch is on.
