Rounding Fractions

If Fraction–display mode is active, the RND function converts the number in the X–
register to the closest decimal representation of the fraction. The rounding is done
according to the current /c value and the states of flags 8 and 9. The accuracy
indicatior turns off if the fraction matches the decimal representation exactly.
Otherwise, the accuracy indicatior stays on, (See "Accuracy Indicators" earlier in
this chapter.)
In an equation or program, the RND function does fractional rounding if Fraction–
display mode is active.
