and 9. The accuracy indicator turns off if the fraction matches the decimal
representation exactly. Otherwise, the accuracy indicator 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.
Example:
Suppose you have a 56

/
4
–inch space that you want to divide into six equal
sections. How wide is each section, assuming you can conveniently measure
1
/
16
–inch increments
?
What's the cumulative roundoff error
?
