hexadecimal.
You can enter digits by pressing the buttons mentioned in the HOW TO INPUT NUMBERS section.
These numbers can be entered into four different bases:
hexadecimal.
decimal.
octal.
binary
system.
A number shown into the output display can be easily converted from a numeric base to another by simply changing the base on the fly.
When working with pure decimal numbers, the user can enter the numbers in two ways:
Normal mode: each number is entered its integer part and, eventually, its fractional part.
Exponential mode: the number is entered by typing a mantissa and then an exponent. This method allows you to write very big or very small numbers that you would not be able to type in a different manner.
You can use it only when the calculator is configured in scientific mode.
However, there are some limits even when you work with exponential notation.
These limits are:
-1.79769313486231570e+308 <= x <= -2.22507385850720140e-308
2.22507385850720140e-308 <= x <= 1.79769313486231570e+308
The exponential input mode is activated by the
button.
After the mantissa has been typed, by pressing this button you will be able to enter the exponent.
When the support for GNU multi-precision libraries is activated, these limits rise greatly to 64 displayed digits for the mantissa and 8 digits for the exponent, both with sign.
When the calculator is in [HEX], [OCT] or [BIN] state, it's possible to apply a masking for limiting the range of the numbers.
Four range are available:
It limits the integers to 64 bit numbers.
It limits the integers to 32 bit numbers.
It limits the integers to 16 bit numbers.
It limits the integers to 8 bit numbers.
