My program won't stop running and I cannot figure out why.

frac=0.525;
b=7;
A=[frac*b];
F=[floor(frac*b)];
frac=A(1)-F(1);

while frac-floor(frac)~=0 
    A=horzcat(A,frac*b);
    for i=1:length(A)-1
        if abs(A(i)-A(length(A)))<10^(-5)
            sprintf('This is a repeating fraction in base %d',b)
            break
        end 
    end
    F=horzcat(F,floor(frac*b));
    frac=A(length(A))-F(length(F));
end
A
F

break only breaks one level. It would leave the for but not the while at the same time.
