Integer values

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).

Methods
