Complex vs. real results of log(b,a)
Answered
Hello,
when i type "log(2, 8)" in Geogebra Classic (Windows 10, v6.0.620.0offline), i get the result "undefined".
When i type the same in Geogebra CAS (Windows 10, v6.0.620.0offlinecas), i get the complex result "(ln(8)+i*pi)/ln(2)". When i use the aprroximatebutton, the result turns to "?".
Is this behaviour intended? Unfortunately i cannot find an option to enable/disable complex results  this would be great for introducing the logfunction for the first time. Would it be possible to integrate this? Or is this option already there and i have missed it?

If you make a complex number eg z_1 = 1+2 ί then you can use ln(z_1)
Complex numbers aren't supported for the other "log" functions in the Algebra View
