Subtract short 

Format 

ssub 

Forms 

ssub = 67 (0x43) 

Stack 

..., value1, value2 -> ..., result 

Description 

Both value1 and value2 must be of type short. The values are popped from the operand stack. The short result is value1 - value2. The result is pushed onto the operand stack. 

For short subtraction, a - b produces the same result as a + (-b). For short values, subtraction from zeros is the same as negation. 

Despite the fact that overflow or underflow may occur, in which case the result may have a different sign than the true mathematical result, execution of a ssub instruction never throws a runtime exception.
