Question about Canon P170-DH Calculator

1 Answer

The calculator is rounding all of my results. I think this is a feature made active by the 5/4 button but I can't seem to turn it off.

You cannot. You must choose either round up, round down or round off (5/4) position, and then set the decimals switch. You would usually use round off (5/4) and decimal set to 2.

What does the 5/4 and F mean on the display screen?


F is for floating decimal. If you do a calculation, it will present the results without rounding. For example, 1/2 would be displayed as 0.5, whereas 1/8 would be displayed as 0.125.

The 5/4 rounds the results. For example, if the number of decimals is set to 0, 1/2 is 1. Similarly, if the number of decimals is set to 2, 1/8 is 1.3.

Good luck,

Paul

How can i round to the hundreds or thousands?


Put the calculator in scientific display mode (SHIFT>MODE(Setup)>FIX. You will be asked to enter the number of fixed decimal digits. Enter 2 for hundredths, and 3 for thousandths. To round to the nearest hundreds or the nearest thousands, do it by hand as follows.
For hundreds
Locate the hundred digit. Let it be h.
If the next digit (the tens digits is less than 5 replace the 10 and unit digits each by 0. Your result will look like ...h00.
If the 10s digit is 5 or above (5, 6, 7, 8, 9) you must round up by increasing the hundreds digits by 1. Your result will look like ...(h+1)00
For thousands
Let the thousand digits be t
If the hundreds digits to its right is less than 5, replace it and the digits following it by 0. Your result will look like ...t000.
If the hundreds digit is 5 or higher, increase the thousands digits by 1 and replace the hundreds, tens, and units digits by 0. You result will end with (t+1) 000
Note if (h+1) or (t+1) give you 10, put a zero at their positions and increase the digit to the left by 1.
Example. 78997 to the nearest hundreds 78997 becomes 789(9+1)0 or 78(9+1)00 or 79000

How do I program tax rate into my calculator?
Non-printing models (also applies to HR-8TE printing calculator):

1. Press [AC]
2. Hold [SET/%] key for about 2 seconds
3. Press [TAX+]
4. Input the tax rate
5. Press [SET/%]


Printing models (except HR-8TE):

1. Have calculator in "print" mode
2. Press [CA]
3. Hold [SET/%] key for about 3 seconds
4. Input the tax rate
5. Press [TAX+]
6. Press [SET/%]

^Top What features do our calculators have?
The attached chart shows comparisons of the different calculator models. This includes graphing, scientific and printing calculators. download the chart here
^Top What is the [F CUT 5/4] switch or [DEC] F, 0, 2 button for?
The HR-8TE/HR-8TM have a [DEC] key with F, 0, 2, and 5/4 over it, while many other calculators models have a switch labeled [F CUT 5/4].
The button or switch can control rounding off to a certain number of decimal places. F is floating point (no F indicator on screen), 0 rounds off to 0 places after decimal point, and 2 rounds off to 2 places after decimal point.
The 5/4 applies to either the 0 or 2 modes, and describes the type of rounding off that is performed. The calculator will round down if the digit after the one you are rounding to is 4 or lower, and round up if the digit is 5 or higher.
^Top What is the [5,4,3,2,1,0 ADD (2)] switch used for?
This switch is used to determine how many decimal places your answer is displayed in.
ADD (2) is often used for monetary calculations, so that it is not necessary to enter the decimal point. It is automatically placed two decimal places from the end for cents. For example, entering 123 will display as 1.23.

The manual for the Canon P1-DHV is online at http://www.usa.canon.com/app/pdf/calculator/P1-DHV_G_USA_HWB.pdf>.
When the display shows "5/4", the calculator is doing 5/4 rounding which means: 5 or above round up, 4 or below round down. To control rounding press the "5/4" key.
When the display shows "E" the calculator could not complete a calculation. It can be because of dividing by 0, or because the total exceeded 1 trillion, or because the operator entered calculations faster than the calculator could complete them. Press the CI/C key to clear it.
I can't explain why you are not getting a total on the tape. Try the following example from the manual exactly as shown, and let me know if your tape shows the total.
  1. Clear the calculator (press [CI/C])
  2. Choose 5/4 rounding (press [5/4] until "5/4" displays)
  3. Choose add mode (press [DEC] until "A" displays)
  4. Choose cost-sell-margin mode (press [B-T] until "B" displays)

There should be a switch that has 5/4 on it. This is the rounding switch. Place it in the Up position to round all numbers up, 5/4 to round down when the next digit is less than 5 and round up when 5 or greater, and the down position to always round down.
