Decimal numbers are real numbers. In C and C++ we use the float, double and long double data types to represent real numbers.
A loss of precision error occurs when you use a variable of a data type that holds more decimal values than the type of the variable you are converting/inserting to.
Double/Decimal- Used to store number with decimal placesFor ExampleDim a As Doublea = 12.64lblDisplay.Text = "The Double value store in the variable is" & aEnd Sub
Use a double or a float data type. While these are suitable for most floating point purposes, there may be times when you need to deal with extremely small or extremely large numbers with a higher degree of accuracy than is possible with the built-in types. In these cases you must either define your own data type or use a third-party data type. For instance, calculating the millionth decimal digit of pi cannot be achieved with the built-in types alone.
A computer programmer can use fractions in his/her program simply by turning the fraction into a decimal. In a language like java, there is not extensive support nor a primitive data type for fractions, but you can store fractions as their decimal equivalents in things such as floats and doubles.
char data type
To type a decimal point, you use the period key. .
The best data type for storing the price of an item is typically a decimal or a fixed-point type, as these can accurately represent monetary values without the rounding errors associated with floating-point types. Using a decimal type allows for precise calculations, which is crucial in financial applications. Depending on the programming language or database, you might use types like DECIMAL, NUMERIC, or MONEY. This ensures that calculations involving prices remain accurate and consistent.

A column of numbers containing a decimal point, like prices.
In Access, you use data type. In Word and Excel, you use data validation.
char data type
To get decimal places use the float data type instead of the int data type. For example: int number; is replaced with : float number; To display the float using printf use the formatting code %f: printf("%f",number); OR: printf("%f",1.11);
