expressed in the following number of digits:
Binary: 16 digits
Octal: 10 digits
Hexadecimal: 10 digits
If you enter a number exceeding the range specified above for
calculations or conversions, the calculator will return an error.
If the answer exceeds the above range, the calculator will also
return an error.
Decimals can be used for DEC mode only (. cannot be used
in the other modes). If you convert decimal values to binary,
octal, or hexadecimal number, the decimal part is discarded and
only the integer part is converted.
When numerical values of binary, octal, and hexadecimal modes
are negative, the display is switched to complements of 2.
