Multiplication is one of the four primary arithmetic operations. The operator * (asterisk) operates on two operands to produce the product.
product = operand1 * operand2;
- product: variable. Allowed data types: int, float, double, byte, short, long.
- operand1: variable or constant. Allowed data types: int, float, double, byte, short, long.
- operand2: variable or constant. Allowed data types: int, float, double, byte, short, long.
int a = 5; int b = 10; int c = 0; c = a * b; // the variable 'c' gets a value of 50 after this statement is executed
※ NOTES AND WARNINGS:
- The multiplication operation can overflow if the result is bigger than that which can be stored in the data type.
- If one of the numbers (operands) are of the type float or of type double, floating point math will be used for the calculation.
- If the operands are of float / double data type and the variable that stores the product is an integer, then only the integral part is stored and the fractional part of the number is lost.
float a = 5.5; float b = 6.6; int c = 0; c = a * b; // the variable 'c' stores a value of 36 only as opposed to the expected product of 36.3
