Same issue for other versions. 
Please, check ceil, ceiling and floor functions. Example is correct, but
description is wrong. 

For ceil in docs
Description: smallest integer not less than argument. 
Example: ceil(-42.8) = -42

But -42.8 < -42
So, description should be "Biggest integer".

Vice versa for floor.
