Consider the following: In[1] := 1 a / 1 Out[1] := a In[2] := 1.0 a / 1.0 Out[2] := 1. a Now consider these identities: In[3] := (1 / 1) == 1 Out[3] := True In[4] := (1.0 / 1.0) == 1.0 Out[4] := True In[5] := (1 / 1) == 1.0 Out[5] := True In[6] := (1.0 / 1.0) == 1 Out[6] := True Given that it is clear mathematically that I want the answer to In[2] to evaluate to just "a", and given that Mathematica is clearly recognizing that 1.0 / 1.0 is the same as 1 / 1, can someone please tell me why Out[2] contains the premultiplier "1." and how to eliminate it in expressions that might contain this superfluous unit multiplier in various places.
