Canon F-715SG | Math ERROR | 2011 | User:Yuri |

-The Casio fx-21 gives the error, "E" after the exponent operation is input, and before the zero can be given as the exponent.

-On the HP 45, raising any number to the power of zero is specifically listed in the manual's Operating Limits section as an "improper operation" and will return an error.

## e^(iπ)+1[edit | edit source]

The expected result of entering e^(iπ)+1 is 0, however the internal precision/rounding of many calculators will create nonzero results. If your has a CAS mode, check to see if it produces a nonzero result, if so, add it to the table, but if the CAS result is 0 do not add it to the table, as it is likely a constant in the CAS software.
