Re: ModuloHi Leroy; So the answer is 1. For 4+5i mod 3; So the answer is 1  i. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20121026 22:36:06
Re: ModuloI didn't really understood the first method and it seems to me the second one could be (4+5i)3(1+i)=1+2i #4 20121026 22:40:30

Re: ModuloHi; I have been interpreting the int as the greatest integer. I would say to be careful with the work done above. I can find no standardization for that formula for complex numbers. As a matter of fact some say floor or int are not defined for complex numbers. Others define them differently than Mathematica does. In mathematics, you don't understand things.

Re: ModuloInteresting, I never thought about modular arithmetic with complex numbers. #8 20121027 03:25:31
Re: ModuloI think,as complex number is also a number,so it should have all properties of normal numbermod,factorial,floor,ceil,ratio,integer part,... #9 20121027 03:39:50
Re: ModuloNot necessarily, there are differences. For one thing the mod function is different. In mathematics, you don't understand things. You just get used to them.
