Would it help if I told you that all the precision you are apparently looking for has no meaning?. In any number resulting from a scientific calculation only a limited number of digits are truly significant.
If you are entering
characters (numbers, symbols, letters, etc.) the calculator keeps accepting them until its memory is full. At this point the cursor changes and go from a solid rectangle to a checkerboard-like rectangle, and you cannot enter anything anymore.
But if you are calculating some meaningful
expression, the calculator displays the result according to the display mode you selected: Normal, Scientific, or Engineering). However, even in normal mode, if a number is too small, or too large, the calculator displays it in scientific format. Scientific format
This format is as follows
- A minus sign if result is negative. If positive (+) is omitted.
- One digit
- Decimal mark (.) or (,) according to configuration
- A certain number of decimal digits (maximum 9)
- The E to symbolize ( times 10 to the power of)
- A minus sign (if exponent is negative), nothing if positive
- A maximum of 2 digits for the exponent of the power of 10. The maximum exponent you can have is 99
Let us count the number of possible characters in a display
-1.123456789E-12. That is 16 character slots.
Try playing with the number 987654321123456. All you will see is 9876543211E12. The 23456 sequence disappears, and all that "precision" is lost. Why, may I ask, should you worry that your calculator is not displaying more that 13 characters on the left.
This is what I understood from your one-liner of a question. And because it is a rather cryptic one-liner, I may have gotten the whole problem wrong. If that be the case, do not just shoot down the answer, post a comment to the solution describing what you are trying to do.
If it is a bona fide worthwhile concern, I will do my best to help you with it. If on the other hand, it is jus plain idle doodling I will leave it at that.
