I want so simplify a certain value(a number) but when I use vpa(debt) I get this error [ Undefined function 'vpa' for input arguments of type 'double'.]

clear;
money_borrowed= 1000
m = money_borrowed
annual_interest= 10/100
a = annual_interest
time_passed_for_payment_in_year= 2
t = time_passed_for_payment_in_year
debt= m * (1+ a/12)^(12*t)
s=vpa(debt)

format bank
Q = @(v) sym(v);  %convert number to symbolic number
money_borrowed = Q(1000)

money_borrowed = 

1000

m = money_borrowed

m = 

1000

annual_interest= Q(10)/100

annual_interest = 

a = annual_interest

a = 

time_passed_for_payment_in_year = Q(2)

time_passed_for_payment_in_year = 

2

t = time_passed_for_payment_in_year

t = 

2

debt= m * (1+ a/12)^(12*t)

debt = 

s = double(debt);
s

s =

Thanks I figured it out and I even tried your code and it worked.
