So would that not be 120/2.718281828?

Or you can do a quick mental approximation by 120/2.7=40/0.9=44.4

If you want to refine it, subtract 2/300 of the calculated value (mentally if you want) to get 44.15 Accurate value is 44.14553294057308

As long as it is between 44 and 45, the floor function will convert it to 44. We need additional accuracy to get the lower bound so it doesn't go below 44.
