Question about Calculated Industries Construction Master IV 4045 Calculator

When I press a number, say, 2 feet 3 1/2 inches, the calculator automatically rounds the number up to 2 feet, 4 inches. I have a Construction Master IV which is about 8 years old.

8 & 23/100 or 823/100

Since 23 is a prime number it can't be divided down, so that's as simple as that fraction can become.

If you're also doing rounding though, then it would become 8 & 25/100 or 8 & 1/4

First, bear in mind that the calculator is going to round numbers eventually, as it can only show a finite number of digits.

You have some control over where and how this rounding takes place. Press [mode], down-arrow, down-arrow, then right-arrow to the choice of decimals desired. Press [enter] to select it.

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

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.

This is a markup on price procedure. The formula is as follows:

Markup%=(Markup Price-Cost)/(Markup Price)

Make sure that you are following the correct procedure.

Adding 10%: 200 [×] 10 [%] [+]

Subtract 10%: 200 [×] 10 [%] [-]

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.

Press the MODE key a certain number of times, until you reach a screen that displays FIX SCI NORM and numbers 1, 2, and 3 under them. Press 1 key to select the FIX display format, then enter a number between 0 and 9 to set the number of decimal digits you want to keep in your result. In your case the calculator is already rounding so you should select a reasonable number of digits say 2 to 3.

MODE (a certain number of times ....) 1 (FIX) 3 will keep three decimal digits in the results.
