ceiling takes a single numeric argument x and returns a numeric vector
containing the smallest integers not less than the corresponding elements of
x. \
floor takes a single numeric argument x and returns a numeric vector
containing the largest integers not greater than the corresponding elements
of x. \
trunc takes a single numeric argument x and returns a numeric vector
containing the integers formed by truncating the values in x toward 0. \
round rounds the values in its first argument to the specified number of
decimal places (default 0). \
signif rounds the values in its first argument to the specified number of
significant digits. \
The functions are applied to the spectral data, not the wavelengths. The
quantity in the spectrum to which the function is applied depends on the class
of x and the current value of output options.
