Question

Python problem: Infinite loop

Answer 1

annualInterestRate=float(raw_input("enter a number: "))
balance=float(raw_input("enter a number: "))

monintrate=annualInterestRate/12.0
lowermonthpay=balance/12
uppermonthpay=(balance * (1+monintrate)**12)/12.0
monthlypayment=1


epsilon=0.2
minpay=(lowermonthpay+uppermonthpay)/2.0


while minpay >= epsilon:
if balance < 0:
uppermonthpay=minpay
else:
lowermonthpay=minpay
minpay= (lowermonthpay+uppermonthpay)/2.0

print "Lowest Payment: " + str(minpay)
