SOURCE: Display a decimal point
Turn the calculator off, then press and hold down the .(decimal key) while you press the on button. Doing so again sets the calculator to use the original digit separators in the display

To change the ´comma´, make sure the calculator is switched to off, press (.) key and maintain, switch the calculator ON. This operation changes dot to comma and vice-versa.

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.
