Doing some toy problems to get used to Matlab for university.
The following is the program:
a=rand(2,2);
c=1;
cmax=2;
r=1;
rmax=2;
while r<=rmax
while c<=cmax
a(c,r)=round(a(c,r),2);
a(c,r)*100;
c=c+1;
end
r=r+1;
c=1;
end
fprintf ('numero casuale: %i \n' ,a)
I expected the output to be something like:
numero casuale: 40
numero casuale: 80
numero casuale: 24
numero casuale: 12
But it turned out like:
numero casuale: 4.000000e-01
numero casuale: 8.000000e-02
numero casuale: 2.400000e-01
numero casuale: 1.200000e-01
Why did it divide the number by 10 and why did it add so many zeroes. How do i fix the outputs.

a=rand(2,2)
c=1;
cmax=2;
r=1;
rmax=2;
while r<=rmax
while c<=cmax
a(c,r)=round(a(c,r),2);
% a(c,r)*100; << your original code isn't changing a here
a(c,r)=a(c,r)*100;
c=c+1;
end
r=r+1;
c=1;
end
format long g
a-round(a)
fprintf ('numero casuale: %i \n' , a);
fprintf ('numero casuale: %i \n' , round(a)); % round a again to handle floating point precision issues
