Consider the following equation:(adsbygoogle = window.adsbygoogle || []).push({});

e^{iπ}= -1

Is π in that equation just a number or do I need to interpret it as radians ?

I mean, if I defined a 'diameterian' so that π diameterians would make the full circle, would the above equation still be correct ?

Thanks
