The third example,
AI
B,
can duplicate the first
or
second examples,
even though A and B represent floating point numbers. The integer numbers
would be held in floating point form, however.
A%I
B%
could exactly
duplicate either of the first two examples.
Exponentiation
(t).
The up arrow specifies that the operand on the left
of
the arrow
is
raised to the power specified by the operand on the right
of
the arrow.
If
the
data
(or operand) on the right is
2,
the number on the left is
squared;
ifthe
data
(or operand)
on
the right
is
3,
the number on the left
is
cubed; and so on. The exponent can be any number, variable, or expression,
as long as the exponentiation yields a number in the allowed floating point
range. For example, .
