REFERENCE
Since this result is 5/16" less than the original 8'-
10 3/4", YOU must lay out each riser a hair more
than 8 3/16.
Remember:
Only calculations using the DIVISION
function can produce an error. The error will never
exceed 1/32", so you only need to check the result
of such calculations if you intend to multiply it by
a large enough number to accumulate a significant
error.
ERROR / OVERFLOW
An error/overflow condition occurs when the result
of a calculation has more than 8 digits to the left
of the decimal point, or when you attempt to divide
a value by zero.
An error/overflow condition is indicated by the
"
ERROR
" label in the upper right corner of the
display. You must clear the calculator display by
pressing the
CE
C
key twice before continuing
operations. Clearing an error/overflow condition
will not clear values stored in the memory registers.
CARE
Don't leave calculator in direct sunlight for long
periods, or store it where excessive temperatures
