In exact mode, any result that is not a whole number is displayed in

fractional or symbolic form. For example, 4 ~ 2 will yield 2 (because 2 is a

whole number), while 5-^2 will yield 5/2 (since 2.5 is not a whole

number).

Similarly, sin(n/4) yields Jl/2 rather than 0.707106781185.

Further examples are given in “Conunand line calculations” on page 2-24.

Exact mode

Note that you can force the calculator to yield an approximate

answer while in exact mode by:

® entering at least one integer as a real nimiber—that is, by

following the integer with a decimal point—see “Integere and

real numbers” on page 2-8, or

* pressing 0 piJM) rather than (ENTffl) to get the result.

Approximate mode

In approximate mode, all numeric results are displayed in floating-point

form where possible.

For example, sin(Tx/4) yields.707106781185 rather than Jl/2.

Further examples are given in “Conunand line calculations” on the next

page.
