Description

Because floor is a static method of Math, you always use it as Math.floor(), rather than as a method of a Math object you created.

Examples

The following function returns the floor value of the variable x:

If you pass 45.95 to getFloor, it returns 45; if you pass -45.95, it returns -46.
