I don't understand why 7<7.0?

Answer 1

7<7.0 is the same as 7<7. It is a bit confusing using two different data types, but it will outputs false since 7 is equal to 7 and not smaller...

Answer 2

Nope, it's not :)

Answer 4

7<=7.0

Answer 5

numbers with floating point may have very small errors. In basic calculations those errors may come out as 7.0000000000000001 or 6.9999999999999999. That's it.
