There are mainly 5 Arithmetic Operators in Java. The Multiplication operator performs multiplication between two entities on either side of the operator. The Division operator performs division and returns the quotient value of the division. The Modulo operator returns the remainder after dividing the two operands.

The SUM() and AVG() functions return a DECIMAL value for exact-value arguments (integer or DECIMAL), and a DOUBLE value for approximate-value arguments (FLOAT or DOUBLE).

What is the difference between int, char, float & double data types? Integer data type allows a variable to store numeric values. The storage size of int data type is 2 or 4 or 8 byte. ... Double data type is also same as float data type which allows up-to 10 digits after decimal.

Array is different from ordinary variable because Array holds multiple values,whereas an ordinary variable hold a single value.It is true when the elements of the array are treated as individual entities,and when the variables such as an int.It is not generally right to distinguish between a variable and an array.

Unlike C/C++, however, short int and long int are not valid data types in Java. In addition, signed and unsigned do not have any special meaning in Java. The floating-point data types are float and double.

Though both float and double datatype are used to represent floating-point numbers in Java, a double data type is more precise than float. A double variable can provide precision up to 15 to 16 decimal points as compared to float precision of 6 to 7 decimal digits.

Multiplying decimals is the same as multiplying whole numbers except for the placement of the decimal point in the answer. When you multiply decimals, the decimal point is placed in the product so that the number of decimal places in the product is the sum of the decimal places in the factors.

format("%. 2f", 1.23456); This will format the floating point number 1.23456 up-to 2 decimal places, because we have used two after decimal point in formatting instruction %. 2f, f is for floating point number, which includes both double and float data type in Java.

1) Float and Double are floating binary point types while decimal is a floating decimal point type. 2) Precision difference for float is '7' digit for double is '15' to '16' digit and for decimal is '28' to '29' digits.

Difference is at . Math. rint() returns double. So it can be said that Math. round() favors mid-point(0.5) for higher value.

Single Precision is a 32-bit type; Double Precision is a 64-bit type. Accordingly, Doubles store a much broader range of values, and with much more precision. The floating point format is comprised of a sign bit, exponent bits (which give you range) and fraction bits (which give you numerical precision).
