◕ Mixed Arithmetic Expressions in Java.

- Let have an example first.

float firstTemp = 10.3;

double secondTemp = 15.4;

long averageTemp = 0;

averageTemp = ( firstTemp + secondTemp ) / 2;

In the above case we have mixed three types of floating point number.

These are **float, double, long.**
If we want to find the **averageTemp** then what type it wii be?

Will it remain as **long ** or it will convert to some other type?

There are some rules for this.

■ 1) If either operand is of type double, the other operand will converted to double before the operation is carried out.

■ 2) If either operand is of type float, the other operand will converted to float before the operation is carried out.

■ 3) If either operand is of type long, the other operand will converted to long before the operation is carried out.

◕ Now what will happen if **type int, short, byte** are mixed?

- In that case they will convert to **type int** and will use 32-bit arithmetic to produce the result.
