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).
a RasterLayer object
a RasterLayer object
integer indicating the precision to be used
