Two separate issues here.

The C indicates the calculator is using compound interest for the odd period. To switch to simple interest, press STO EEX

To switch the radix mark, turn the calculator off, press and hold the . (decimal point) key, press the ON key, then release both keys.

Define algebra:decimal


Decimal is the base-10 notational system for representing real numbers. The expression of a number using the decimal system is called its decimal expansion, examples of which include 1, 13, 2028, 12.1, and 3.14159.

Each of the arabic numerals 0 to 9 is called a decimal digit, and the period placed to the right of the units place in a decimal number is called the decimal point (or, in the case that a comma is instead used for this purpose, the decimal comma).


The decimal is a way of managing numbers that has ten as a starting point, or base. It is sometimes called the base ten or denary numeral system. The word "decimal" is also used instead of the word "period" to point out the dot that is sometimes used separates the positions of the numbers in this system. Almost everyone uses this nowadays and prefers the convenience of it probably because it shows up most often in calculations in nature and has "one" as another starting point for the system. The number one is usually the easiest to work with in calculations.

Here is help from the calculator manual.

If you wish, you can set the calculator to display a comma for the decimal point and a dot for the three-digit separator. To do so, turn the calculator off, then press and hold down the [ . ] key while you press [ON]. Doing so again sets the calculator to use the original digit separators in the display.

I just replaced the batteries in my HP 12C calculator and when I turned it back on the display looks like this 0,000. How do I get the display to show decimals instead of a comma?


Hello,
Here is what the manual for the HP 12C Platimum financial calculator says on page 17 of 275

Digit Separators
As a number is keyed in, each group of three digits to the left of the decimal point is automatically separated in the display. When the calculator is first turned on after coming from the factory — or after Continuous Memory is reset — the decimal point in displayed numbers is a dot, and the separator between each group of three digits is a comma. If you wish, you can set the calculator to display a comma for the decimal point and a dot for the three-digit separator. To do so,
turn the calculator off, then press and hold down the [ . ] key while you press [ON] Doing so again sets the calculator to use the original digit separators in the display.


Hope it helps.

500 x 16 reads 8.000,0 instead of 8,000.00


The calculator has two digit-separation marks: The dot [.] and the comma [,].
By default the decimal (radix) mark is the dot, and the comma serves as a 3-digit separator. In European countries (especially France) the radix mark is the comma and the 3-digit separator is the dot.

To switch the marks:
  1. Turn calculator OFF
  2. Press and HOLD the [.] key while pressing [ON].

Decimal point is replaced with comma


Check to see if the calculator is in European mode where the comma is sometimes used rather than the period.
