How do I avoid using the decimal when typing a number with no 0s
All of our other adding machines have a + symbol in the decimal control so that when I am typing 56.23 for example, I don't have to hit the decimal key. This machine doesn't have that + symbol, how can I fix this?
Re: How do I avoid using the decimal when typing a number...
If I am not mistaken you are trying to set your decimal in dollars and cents correct? Well, if I am understanding your question correctly; you move tab that has F 6 3 2 1 0 set that to the 2 and then there is a tab that says "K * A make sure that is set to the A as well. Hope that helps.

Despite the goodies this calculator has, it does not have a key for the percentages.
To convert a decimal number to %, move the decimal mark two places to the right and put the % symbol. 0.257 =0.257* 100%=25.7 %
To convert a percentage into its decimal equivalent, move the decimal mark two places to the left and remove the % symbol.
2.4507E-4 is scientific notation for 2.4507 times ten to the minus 4, or .00024507.
Take the 2.4507 and move the decimal point, to the left if the exponent is negative, to the right if it is positive, the specified number of positions.
If the magnitude of the result is too small or too large, the calculator will automatically switch to scientific notation. Imagine a number that has more than 12 digits to the left of the decimal point. How is that going to fit onto the display? Or a number that is 0 followed by the decimal point followed by 12 0s and then some significant digits?
The selector you are asking about is the "decimal selector". The result displayed/printed, will be in a format according to the position that you have selected as follows:
f = floating (the result will be in the number of decimal places that were entered on the keyboard
4= fixed 4 decimal places (x.0000)
3= fixed 3 decimal places (x.000)
2= fixed 2 decimal places (x.00)
0= fixed 0 decimal places (x)
add 2= (add mode*,fixed 2 places) ($.00)
Note* "ad mode" automatically enters the decimal place when entering the number on the keyboard. If you enter "123", the displayed ammount will be "1.23". If you enter "1", the display will read ".01". This is a useful setting when adding a list of numbers in a dollars/cents format, however, be careful, if entering a whole dollar ammount "three dollars" be sure to enter the decimal point, or enter the number as "300". If you don't, the result will be ".03", instead of the 3 dollars you intended.
First put the calculator in degree mode.
To convert from fraction to a decimal number first enter your fraction or, mixed number. I'll convert a mixed number to a fraction first since, I don't have a key for the symbol that shows that a number is a fraction on my keyboard. Example: [A b/c][A b/c][A b/cd/e][ENTER]
3/2 should be entered at the home screen. While at the Home screen enter, [2nd][FD][ENTER]
1.5 should now be displayed at the Home screen.
As you can see it is really just using the [A b/c] key to enter in your fraction and, [FD] key to do the converting. The [A_b/cd/e] key isn't necessary because, mixed numbers will convert to decimal numbers just like fractions do. I just don't have the key to show a fraction symbol that the calculator uses. So to show that symbol, I used the / symbol with the fraction number.
Decimal Point and Separator Symbols You can use the display setup (Disp) screen to specify the symbols you want for the decimal point and 3-digit separator. • To change the decimal point and separator symbol setting, press the MODE key a number of times until you reach the setup screen shown below. Display the selection screen. (Disp) 1. Press the number key ( 1 or 2) that corresponds to the setting you want to use. 1(Dot): Period decimal point, comma separator 2(Comma): Comma decimal point, period separator
To convert fractions to decimals, and decimals to fractions use the [a b/c] key. If the total number of symbols (num, denom, fraction bar) to display a fraction exceeds 10, the fraction is automatically converted to decimal format.
Hello, The Fix sign on the top of the screen (smaller size) are indicators that calculator is using the FIXed format: All numbers are displayed with a fixed number of decimal digits (in you case it may have been set to 9 decimal digits). You can change that in the setup. The Grad symbol means that the angle unit is set to grad. This too can be changed to degrees or radians in the set up. A sure way to achieve mastery of calculator use is to learn how to configure it to fit the types of calculations to be performed.
Hello, Your TI81 can only perform numerical calculation: It always give uour numbers. The TI89, a more sophisticated calculator, can of course do numerical calculation, BUT ALSO symbolic ones. You ask it for the derivative of sin(x) and it will give you cos(x). Anyway, if you want a decimal result for you calculation above one of the numbers must have a decimal point (instead of writing 2PI write 2.PI.
The TI 89 can do exact calculations. But if you want approximate results any number in the sequence of operations must have the mark of a decimal. Numbers without decimal marks are considered integers, Integer numbers with a decimal mark are treated as floating point numbers ( meaning decimal).
