Description
Both value1 and value2 must be of type long. The values are popped from the operand stack. The long result is value1 - (value1 / value2) * value2. The result is pushed onto the operand stack.
The result of the lrem instruction is such that (a/b)*b + (a%b) is equal to a. This identity holds even in the special case that the dividend is the negative long of largest possible magnitude for its type and the divisor is -1 (the remainder is 0). It follows from this rule that the result of the remainder operation can be negative only if the dividend is negative and can be positive only if the dividend is positive; moreover, the magnitude of the result is always less than the magnitude of the divisor.
Runtime Exception
If the value of the divisor for a long remainder operator is 0, lrem throws an ArithmeticException.
