Overflow Indication; Accuracy - Calculated Industries Construction Master III User Manual

OVERFLOW INDICATION

When you make an incorrect entry, or the an-
swer is beyond the range of the calculator, it will
display the word "Error." To clear an error
condition you must hit the [On/C] button twice. At
this point you must determine what caused the
error and re-key the problem. An "error"
condition will also occur if you enter a math-
ematical impossibility such as division by zero.
Auto-Range — If an "overflow" is created
because of an input and calculation with small
units that are out of the standard 7-digit range
of the display, the answer will be automatically
expressed in the next larger units (instead of
showing "Error") — i.e., 10,000,000 MM cannot
be displayed because it is out of the 7-digit
display, so 1,000,000 CM will be displayed
instead. This auto-ranging also applies to other
dimension units, such as inches to feet, and feet
to yards, etc.

ACCURACY

Your calculator has an eleven digit display.
This is made up of seven digits (normal display)
and four digits for the fraction.
Standard Display — In a standard calcula-
tion, each calculation is carried out internal-
ly to 9 digits and is rounded to a 7-digit
standard display. A 5/4 rounding technique
is used to add 1 to the least significant digit
in the display if the next non-displayed digit
is five or more. If this digit is less than five,
no rounding occurs.
