I have been using python to do algebraic calculations, but at many times when writing 1/2 Python writes 0.5, but I wanted you to write 1/2 and only when needed, convert it to a float.

I'm having a hard time imposing a simplification because Python doesn't recognize 32.0 as being 32, in short example situation where I have.


Since the answer could be

If you want to do symbolic math, there's a python-module called sympy.

In order the achive what you want here, you could do the following:

from sympy.abc import x
from sympy import simplify
f = (32 - 64 * x)**2 / 4096
print(f) # (32 - 64*x)**2/4096
print(simplify(f)) # (2*x - 1)**2/4

  • $\begingroup$ @PEDROMORAIS, it does have simplification. I suggest that you check SymPy documentation. If you have similar questions you could use the mailing list or Gitter. $\endgroup$

  • $\begingroup$ @nicoguaro Checking the SymPy documentation. I found the command nsimplify()which find a simple representation for a number or, if there are free symbols or if rational=True, then replace Floats with their Rational equivalents. If no change is made and rational is not False then Floats will at least be converted to Rationals. $\endgroup$
