Floor and Ceiling is a way in mathematics to round a decimal number either lower or higher to the whole number, regardless if the fractional digits (to the right of the decimal point) are equal to or greater or lesser than 5.
Floor:
Floor brackets look like this: ⌊x⌋
Where x would be the decimal number
Example:
⌊4.8⌋ = 4
We ignore the fact that 8 is greater than 4 (basic rounding), so we actually round down, contrary to basic rounding, because we are using floor.
Ceiling:
Ceiling brackets look like this: ⌈y⌉
Where y would be the decimal number
Example:
⌈6.2⌉ = 7
Again, we ignore what was earlier said.
And that's all there is to it. Simple, aye?
