  1. Press Mode.
  2. Use down arrow to reach Float.
  3. Use right arrow to highlight 3, 4,5,6,7,8,9
  4. Press ENTER to validate.
I have no stake in the this matter, but you should keep in mind that in scientific problems your precision is as good as that of the least precise quantity. That is why one talks about significant digits.

    Why the sour rating? Did I not answer completely your question. Let us see what may be missing? Point3 is not clear, It should have been "Use right arrow to highlight 3, 4,5,6,7,8, OR 9". Sorry, but anybody would have understood that one can only highlight one of the numbers. The largest number of decimal digits you can have is 9.

HP 12 C display does not show entire numbers. How do I fix?


If you mean it is not showing everything after the decimal point, you can change that by pressing the [f] key followed by the number of decimal places to display. For example, to restrict it to 2 places, press [f][2]. If you want to see 4 places, press [f][4].

To show all possible decimal places, use the sequence [f][9].
From the manual (http://www.hp.com/ctg/Manual/c00363319.pdf):
"To display a different number of decimal places, press f followed by a digit key (0 through 9) specifying the number of decimal places. In the following examples, notice how the displayed form of the number inside the calculator - 14.87456320 - is rounded to the specified number of digits."


25096057-rvrejqbjq4zuw4cbinsyjvsy-5-0.png "Although nine decimal places were
specified after f, only eight are
displayed since the display can
show a total of only 10 digits. "
The standard display format, plus the specified number of decimal places, remain in effect until you change them; they are not reset each time the calculator is turned on. However, if Continuous Memory is reset, when the calculator is next turned on numbers will be displayed in the standard display format with two decimal places
shown.
If a calculated answer is either too small or too large to be displayed in the standard display format, the display format automatically switches to scientific notation. The display returns to the standard display format for all numbers that can be displayed in that format.

How can i change my calculator so the answer will be in decimals instead of exponents or fraction?


There is a misconception hiding here in your statement. A decimal result on a calculator is often no more than an approximation: Try expressing 1/3 as a finite decimal representation. So, the only exact results that you may get are those displayed as fractions and those with radicals.
Now let us address your question. The calculator has a limited display capability. Any decimal result that is too small or too large to fit in the display window will automatically be displayed in scientific notation (the one with exponents).
If you want exact results, you should set the Input/output to MathIO. Even then, if the expression requires more display space than is available, it will be displayed as a decimal number.

No decimal display on TI BA-II calculator


Your BA II PLUS stores numeric values internally to an accuracy of 13 digits. However, the numbers it displays depends on the number of decimal places to which you have it set (choice of 0–9 or floating decimal). To set the number of decimal places displayed to three: hit [2ND][FORMAT][3][ENTER]This setting also continues indefinitely (even though the calculator is turned off and on) until it is changed.

TI-83 plus problem


Hello,
The calculator has limitations. No matter what number of decimal places you specify in the floating mode format, If the absolute value of the number is less than 0.001 the number is displayed in scientific format :
[digit][.][digt][digit] ...up to [digit9] [E][-][2 digit exponent].
Here are somme screen capture that show you that.

4efe901.jpg
6aa6547.jpg
As you can see the two screens overlap. Floating mode is set to 4 decimal places. As long as the absolute value is less than 0.001, the number is displayed in scientific format. However when that absolute value exceeds 0.001 the display reverts to the floating mode format you want.

When you manipulate very small or very large numbers, the floating point format cannot be used because of the limitations of the screen.
In this last screen capture Floating mode is set at 9 decimal places. I entered the electron charge. The line is pretty full.

SETTING UP THE DECIMAL ON NEW 210 TM


Set the +43210F switch to + (or 2).
On some models it is A43210F, then use A (or 2).
+ mode will let you enter numbers (monetary) without the decimal point and assumes cents; 2 mode will just round to 2 decimals, but you must enter the decimal.
