Engineering Format ({  })
ENG format displays a number in a manner similar to scientific notation, except
that the exponent is a multiple of three (there can be up to three digits before the
"  " or "  " radix mark). This format is most useful for scientific and engineering
calculations that use units specified in multiples of 10
kilo–units.)
After the prompt,  _, type in the number of digits you want after the first
significant digit. For 10 or 11 places, press
For example, in the number 

For example, key in the number 

the exponent is a multiple of 3. When you press
is converted to 
and converting the exponent to the next lower multiple of 3.
Key in the number 
displayed value to 
the exponent is a multiple of 3. When you press

three places to the left and converting the exponent to the next higher multiple of 3.
ALL Format ({  })
ALL format displays a number as precisely as possible (12 digits maximum). If all
the digits don't fit in the display, the number is automatically displayed in scientific
format.
SHOWing Full 12–Digit Precision
Changing the number of displayed decimal places affects what you see, but it
does not affect the internal representation of numbers. Any number stored
internally always has 12 digits.
