### Description

These functions take a single RasterLayer argument `x` and change its values to integers.

`ceiling` returns a RasterLayer with the smallest integers not less than the corresponding values of x.

`floor` returns a RasterLayer with the largest integers not greater than the corresponding values of x.

`trunc` returns a RasterLayer with the integers formed by truncating the values in x toward 0.

`round` returns a RasterLayer with values rounded to the specified number of digits (decimal places; default 0).
