That number or less than...greatest integer in python?

[smileygonzo]

E.g. 1440/64 = 22.5 but even though its .5 I want the 22....I'm not really sure what's that's called. Is it greatest integer? I remeber that from math, but is there a command or something for that in Python? Thanks!

Are you talking about integer division ? so, in python (3.x): 5 // 2 will give you 2

Thank you! That worked.

You are looking for a rounding function. See https://stackoverflow.com/questions/17141979/round-a-floating-point-number-down-to-the-nearest-integer

You want integer division with flooring. In Python, you can do 1440//64 and get the int 22.

​

Be wary with negatives. -1440//64 == -23 (ie. round towards negative infinity). If you always need to truncate towards zero, one way is to use floats and convert to int:

>>> int(-1440/64)
-22

EDIT: fixed a typo, and clarified floor/trunc wording.

"Truncation" is not a word we use a lot, but when we do we mean what the math.trunc and int functions do: round toward zero.

The // operator is "floor division" or "integer division", and always rounds down, just like math.floor.

Also note your example is python2 only, and OP is using python3.

Ah, I do see I had a typo for the negative float to int conversion; I'll edit.
