I am able to follow the working...but i needed some clarification. By rounding to the nearest integer...did they mean?

##z=1.2-1.4i## is rounded down to ##z=1-i##?

I can see from here they came up with simultaneous equation i.e

##(1-i) + (x+iy) = \dfrac{6}{5} - \dfrac{7i}{5}## to realise,

##x+iy=\dfrac{1}{5} - \dfrac{2i}{5}##

...the other steps seem clear...any reason why they make use of the so called second summand? One thing i have noted with pure maths- is that its quite easy- the only challenge i seem to use a lot of effort on is understanding the notations and the language used...why did they have to check the other norms i.e for ##a## and ##b## for instance the

##|a|=5^2+14^2##?

...are there cases where the norms may be small...

...I can see gaussian integers in some literature...the bit on the norms is now clearer...Will read on this some more...

cheers.
