This is important because when I try to plot A and B as elements of a matrix with a colormap using imagesc they get very different colors.
Then my questions are:
How to interpret a number such as A=1.000000000000000?
Is it possible to display its nonzero decimals after the 15th zero?
Another important question is that Matlab seems to make this kind of rounding off randomly so many other complex numbers when operated as above produce results sometimes displayed as an exact one or a one follwed by many zeroes.
