[Help: CAS Code] Comparing answers history view
Example #1:
Steps Step 1: root:=√(2.) [enter] 1.41421356237 Step 2: exact(root) == approx(root) [enter] true Where: left(exact(root)) ->1607521/1136689 right(approx(root)) -> 1.41421356237 then 1607521/1136689 == 1.41421356237 -> true now Step 3: approx(root) [enter] 1.41421356237 Step 4: exact(root) [enter] 1607521/1136689 Step 5: Ans == [up][up][up] -> (0) false 1607521/1136689 == 1.41421356237 -> 0 // expr 2 Why two different answers? 1607521/1136689 == 1.41421356237 // expr1 1607521/1136689 == 1.41421356237 // expr2 expr1 same expr2 yes |

RE: Comparing expressions
Si quieres comparar 2 datos, puedes crear un función que identifique si es una 'expresión', en caso de serlo lo evaluas, y puedes realizar la comparación.
