converting to floats

i am not quite sure what I am doing wrong here. basically they want me to make sure my arguments are floats. remind me, just to be sure, a float is an integer but with a value after the decimal, like 2.45, correct?

trial.py 
var1=float(var1)
var2=float(var2)
def add(var1,var2):
  return (var1+var2)

Hi Didier, you are correct in saying floats are (basically) numbers with a decimal point. The reason your code is not working is because you should have converted the arguments to floats inside the function because outside of the function, they do not exist. This is due to function scope. 

def add(var1,var2):
  return float(var1) + float(var2)

If you have any further questions, please leave a comment :)

Thanks,

Haider
