the default if you use 4095 or greater.) This also turns on
Fraction–display mode.
The /c function uses the absolute value of the integer part of the number in the
X–register. It doesn't change the value in the LAST X register.
Choosing Fraction Format
The calculator has three fraction formats. Regardless of the format, the
displayed fractions are always the closest fractions within the rules for that
format.
Most precise fractions. Fractions have any denominator up to the /c
value, and they're reduced as much as possible. For example, if you're
studying math concepts with fractions, you might want any denominator
to be possible (/c value is 4095). This is the default fraction format.
Factors of denominator. Fractions have only denominators that are
factors of the /c value, and they're reduced as much as possible. For
example, if you're calculating stock prices, you might want to see
+
and
+
(/c value is 8). Or if the /c value is 12, possible
denominators are 2, 3, 4, 6, and 12.
Fixed denominator. Fractions always use the /c value as the
denominator—they're not reduced. For example, if you're working with
time measurements, you might want to see
+
(/c value is 60).
To select a fraction format, you must change the states of two flags. Each flag
can be "set" or "clear," and in one case the state of flag 9 doesn't matter.
