These ‘functions’ consist of a set of commonly occurring constants.
Two of them,
MAXREAL and MINREAL are mainly of use to
programmers except for an important influence on the evaluation of
limits (see page
80). They consist, respectively, of the largest and
smallest numbers with which the calculator is capable of dealing, and
are there for use by programmers as a check to ensure that calculations
within a program have not overflowed the capacity of the calculator.
The other three,
π, i, and
e
, are far more easily obtained via the keyboard.
The first,
π, is available via a key on the face of the calculator above the 3 key. The other two , i &
e
, are
easily obtained as lowercase letters via the
ALPHA key, pressing SHIFT first to get lowercase.

This is a set of functions which allow conversion of metric units to imperial and vice versa. The list is not very
extensive but does cover the more common ones. The syntax is the same
for all.
For example, the
ÆC function converts to Celsius from the equivalent
Fahrenheit. To convert 212 degrees Fahrenheit to Celsius just type
ÆC(212). To convert 100 kg to pounds, use ÆLBS(100) as shown in
the screen shot.
The available functions are:
ÆC - converts Fahrenheit to Celsius
ÆCM - converts inches to centimeters
ÆL - converts litres to US gallons
ÆKG - converts pounds to kilograms
ÆKM - converts miles to kilometers
ÆDEG - converts radians into degrees
ÆF - converts Celsius to Fahrenheit
ÆIN - converts centimeters to inches
ÆGAL - converts US gallons to litres
ÆLBS - converts kilograms to pounds
ÆMILE - converts kilometers to miles
ÆRAD - converts degrees into radians
