11.13.4 Subtraction Operator

Visual Studio .NET 2003

The subtraction operator subtracts the second operand from the first operand. The subtraction operator is defined for the following types:

  • Byte, Short, Integer, and Long. If integer overflow checking is on and the difference is outside the range of the result type, a System.OverflowException exception is thrown. Otherwise, overflows are not reported, and any significant high-order bits of the result are discarded.
  • Single and Double. The difference is computed according to the rules of IEEE 754 arithmetic.
  • Decimal. If the resulting value is too large to represent in the decimal format, a System.OverflowException exception is thrown. If the result value is too small to represent in the decimal format, the result is 0.
