How can I round to 2 decimal places

So I am trying to round my number my current output is giving me 4 decimal places after the period 127.1234 im trying to make look like this 127.12. i have tried all formats of rounding and have multiple by 100 and divide by 100 nothing really seems to work.

oad a02_data.mat

sub_tot = sum(purchases(:,1));
sub_tot_0 = 0;
sub_tot_1 = 0;
sub_tot_2 = 0;
tax_tot_0 = 0;
tax_tot_1 = 0;
tax_tot_2 = 0;

L = length(purchases(:,1));


for ind = 1:L
    if purchases(ind,2) == 0
        sub_tot_0 = sub_tot_0 + purchases(ind,1);
         tax_tot_0 = tax_tot_0 + tax_rates(1)*purchases(ind,1);
    
    elseif purchases(ind,2) == 1
        sub_tot_1 = sub_tot_1 + purchases(ind,1);
        tax_tot_1 = tax_tot_1 + tax_rates(2)*purchases(ind,1);
        
    elseif purchases(ind,2) == 2
        sub_tot_2 = sub_tot_2 + purchases(ind,1);
        tax_tot_2 = tax_tot_2 + tax_rates(3)*purchases(ind,1);
    end
end

tot = sum([tax_tot_0,tax_tot_1,tax_tot_2,sub_tot_0,sub_tot_1,sub_tot_2]);

format short
disp('subtotal for purchases in tax rate 0')
disp(round(sub_tot_0*100)/100)
disp('Total taxes in category 0')
disp(round(tax_tot_0*100)/100)

disp('subtotal for purchases in tax rate 1')
disp(round(sub_tot_1*100)/100)
disp('Total taxes in category 1')
disp(round(tax_tot_1*100)/100)

disp('subtotal for purchases in tax rate 2')
disp(round(sub_tot_2*100)/100)
disp('Total taxes in category 2')
disp(round(tax_tot_2*100)/100)

disp('Subtotal is')
disp(round(sub_tot*100)/100)
disp('Total is')
disp(round(tot*100)/100);
