The maximum and minimum code sizes for each operation
listed in Table 10 are approximate and will vary according to
use in an equation. Code sizes are shown in bytes. These
numbers should be used only to estimate the size of a function
block. The actual size of the function block can always be
checked by compiling the function block and observing the
actual size reported by the compile operation.
