calculate annual and monthly interest

interest = int(float(raw_input("Interest Rate: ")))
monintrate = int(float(( interest / 100.0 ) / 12))
annintrate = int(float(interest / 12))

print "Interest: ",interest
print "Mon Int Rate: ",monintrate
print "Ann Int Rate: ",annintrate

hello, i would like to properly calculate the above variables as decimals but for whatever reason i cant get it work correctly. can someone point me in the right direction?

You need to get rid of the int

interest = float(raw_input("Interest Rate: "))
monintrate = round((interest / 100.0)/12, 4) """ will give 4 decimal places"""
annintrate = round((interest / 12), 4)       """ will give 4 decimal places"""

print "Interest: ",interest
print "Mon Int Rate: ",monintrate
print "Ann Int Rate: ",annintrate

Gives the following:

Interest:  5.0
Mon Int Rate:  0.0042
Ann Int Rate:  0.41667

Remove the int before the variables so you can get decimals

interest = float(raw_input("Interest Rate: "))
monintrate = float(( interest / 100.0 ) / 12)
annintrate = float(interest / 12)
