results in 5
results in 1600
results in the floating point
number assigned to variable
A being divided by
the floating point number
assigned to variable B
results in 400 being divided
by the floating point number
represented by label XR
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, .
