New issue 2828 by [email protected]: primitive() problem
http://code.google.com/p/sympy/issues/detail?id=2828
Before:
python -c 'from sympy import var; var("x y"); print (4.0*x +
y/2).primitive()'
(1/2, 2*4.0*x + y)
now:
$ python -c 'from sympy import var; var("x y"); print (4.0*x +
y/2).primitive()'
(1, 4.0*x + y/2)

use Add in primitive
In addition, as_coeff_Mul is used to break up the terms. If
gcd ever handles Float then this will still work since as_coeff_Mul
returns the leading Number while as_coeff_mul returns only the
leading
Rational.
Not sure which is correct. But this is related to the pull request:
