Wrong exponential notation used in programming mode

[Martin Rosenau]

In programming mode the calculator is primarily used for doing integer operations.

However integer results are shown in exponential notation and the result does NOT represent the correct integer!

Example:

- Calculate 2^40.
- The result 1.099511628×10^12 is shown which is the integer 1099511628000
- However the correct result is 1099511627776, not 1099511628000

A possible change which might solve this:

Change the selection:
- Binary
- Octal
- Decimal
- Hexadecimal

To:
- Binary
- Octal
- Scientific decimal
- Programmer decimal
- Hexadecimal

"Scientific decimal" would behave like it does today.
"Programmer decimal" would behave the same way as Binary, Octal and Hexadecimal and display integers like 2^40 as 1099511627776, not as 1.099511628x10^12

The issue seems an upstream one, could you maybe report it to them as well on https://gitlab.gnome.org/GNOME/gnome-calculator/issues ?
