Subtraction is one of the four primary arithmetic operations. The operator - (minus) operates on two operands to produce the difference of the second from the first.
difference = operand1 - operand2;
- difference: 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.
※ NOTES AND WARNINGS:
- The subtraction operation can overflow if the result is smaller than that which can be stored in the data type (e.g. subtracting 1 from an integer with the value -32,768 gives 32,767).
- 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 difference is an integer, then only the integral part is stored and the fractional part of the number is lost.
