Question

In the code below: highly simplified. I get ZeroDivisionError: float division
Any value below one gives errors. Other times 5/365 gives the error.
How do I fix?

import math

def top(  t):
    return ((.3 / 2) * t) / (.3 * math.sqrt(t))


t = 365/365
top= top(t)
print (top)

Answer 1

The problem is here:

t = 365/365

You are dividing two integers, so python is using integer division. In integer division, the quotient is rounded down. For example, 364/365 would be equal to 0. (365/365 works because it is equal to 1, which is still 1 rounded down.)

Instead, use float division, like so.

t = 365.0/365.0
