Forms
isub = 100 (0x64)

Stack
..., value1, value2 ..., result

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

For int subtraction, a - b produces the same result as a + (-b). For int values, subtraction from zero 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 an isub instruction never throws a runtime exception.
