Hello,
Consider the following.
(%i1) r(x):= rationalize(x);
(%o1) r(x) := rationalize(x)
(%i2) r(2 + 3) - r(2) - r(3);
(%o2) 0
(%i3) r(2.1 + 3) - r(2.1) - r(3);
(%o3) 0
(%i4) r(2.1 + 3.2) - r(2.1) - r(3.2);
1
(%o4) ---------------
866076851417430
Is this a bug in arithmetic? Does maxima "assume" that 2.1 and 3.2 are
floating point numbers by default?
If so, how do I declare all numbers and variables to be rational
throughout a session?
TIA,
-sen
